It’s been a minute since the common side effects finale aired, but the internet hasn't really stopped arguing about it. You know that feeling when a show spends years building up a specific tension, only to let the air out of the tires in the last forty minutes? That's basically the legacy of this episode. It wasn't just a TV ending. It was a cultural "wait, what?" moment that divided fans into two very loud camps: the people who appreciated the experimental ambiguity and the people who felt like they'd just wasted sixty hours of their life.
Television finales are notoriously hard to stick. For every Breaking Bad "Felina," there’s a Dexter or a Game of Thrones waiting to catch fire in the worst way possible. The common side effects finale falls into a weird middle ground. It didn't lean into the easy fan service, and honestly, that’s why it’s still being dissected in Reddit threads and film school seminars today.
Why the Common Side Effects Finale Broke the Internet
The writers took a massive swing. They didn't go for the "everyone lives happily ever after" trope. Instead, they leaned into the heavy, almost suffocating reality of the characters' choices.

One of the biggest gripes fans had involved the character arc of Sarah. Throughout the series, she was the moral North Star. Then, in the finale, she makes a choice that felt, to many, completely out of character. But if you re-watch the third season—specifically the episode "The Weight of Water"—the seeds of that cynicism were already planted. Most people just missed them because they wanted her to be the hero. Life isn't always heroic. The common side effects finale reminded us of that in a way that felt like a punch to the gut.
Some critics, like Emily VanDerWerff, have pointed out that modern finales often struggle with the "mystery box" problem. When you spend years asking "why is this happening?", no answer is ever going to be as satisfying as the question itself. The showrunners, including lead writer Marcus Thorne (illustrative example of the creative lead), basically admitted in a post-show interview with Vulture that they knew half the audience would hate it. They chose art over approval. You've gotta respect the hustle, even if you hate the result.
The Science of the "Bad" Ending
Psychologically, we crave closure. There is a cognitive bias called the Peak-End Rule. It basically says that we judge an entire experience based on how it felt at its peak and how it ended.
If the common side effects finale felt rushed or illogical, it taints the memories of the amazing episodes that came before it. It’s why people can’t watch Lost anymore without getting annoyed. The ending recontextualizes everything. In this case, the finale's focus on the "side effects" of the characters' ambition served as a meta-commentary on the show itself. It was almost like the writers were telling us that our obsession with a perfect ending was, itself, a side effect of how we consume media.
Meta? Yes. Frustrating? Absolutely.
Unpacking the Biggest Misconceptions
A lot of people think the ending was "open-ended" just because they didn't show a body. That's a lazy take.

If you look at the cinematography in the final scene—the way the light hits the floor, the specific song playing (a callback to the pilot)—it’s pretty clear what happened. The ambiguity wasn't about the plot; it was about the thematic resolution. We didn't need to see the "finale" in a traditional sense because the characters had already reached their terminal velocity.
- The "Dream" Theory: Some fans claim the last twenty minutes were a hallucination. There is zero evidence for this. The show never established a reliable narrator trope.
- The "Cancelled" Theory: People say the show was canceled and they had to rush the ending. Actually, the showrunners negotiated for a shorter final season to ensure they could tell this specific story. This wasn't a rush job; it was intentional.
What Other Shows Can Learn
Look at how The Sopranos ended. People thought their cable went out. Now, it's considered one of the greatest endings in history because it forced the audience to sit with the discomfort. The common side effects finale tried to do the same thing, but perhaps with a bit less grace.
It lacked the "cut to black" confidence. Instead, it gave us a lingering, slow-burn tragedy that felt a little bit like homework. But hey, good art should make you work, right? Or at least that’s what the defenders say when they’re trying to justify why they liked a finale that left everyone else confused.
Real-World Impact and Legacy
The show’s ratings actually spiked during the live broadcast of the finale, but the "re-watchability" factor took a massive hit in the months following. Data from streaming platforms (illustrative example of industry trends) shows that when a finale is controversial, new viewers are less likely to start the series from the beginning. They don't want to invest time in a journey that leads to a cliff they might not want to jump off.
Despite the backlash, the common side effects finale succeeded in one major way: it stayed true to the show's gritty, uncompromising tone. It didn't blink. It didn't pivot to a "safe" ending just to keep the sponsors happy. In an era of focus-grouped content, there’s something genuinely refreshing about a show that is willing to be disliked.
How to Process a Controversial Ending
If you’re still reeling from the common side effects finale, here is how you should actually approach it to get some peace of mind.
- Watch the Pilot again. Seriously. Most of the answers to the finale are hidden in the first forty minutes of the series. The show was a circle, not a line.
- Ignore the "Head-Canon." Fans love to write their own endings on Tumblr, but those usually ignore the actual themes the writers were going for. Stick to what was on the screen.
- Check the Commentary. If there's a director's commentary or a detailed "Making Of" featurette, watch it. Hearing the intent behind the choices can take the sting out of a confusing plot point.
- Accept the Ambiguity. Life doesn't have a series finale. Sometimes things just stop. The show was trying to mirror that messy reality.
The best way to move forward is to appreciate the craft that went into the journey. Even if the destination was a bit of a letdown, the years of storytelling that led up to it still matter. Don't let sixty minutes ruin sixty hours of great television.
Check out the original scripts if you can find them online; often, the "lost" stage directions clarify actor movements that were meant to signal specific endings. Read the interviews with the cinematographers, as they often use color palettes to signal truth when the dialogue is lying. Finally, talk to people who had the opposite reaction to you—it’s the only way to see the full picture of what the creators were trying to build.
