All good things must come to an end, and unfortunately for Netflix subscribers, that includes the blossoming romance between Nick (Kit Connor) and Charlie (Joe Locke). The Heartstopper franchise is drawing to a close with Heartstopper Forever, a feature film in lieu of a full fourth season.Like most fans when they first heard the news, I felt cheated. Much like the original graphic novel books by Alice Oseman, Nick and Charlie's story is one best told over time. Two teens grappling with their feelings and identities need time to breathe together, let alone without their smorgasbord of friends who also all have their own delicious narrative arcs.Now I've seen all 114 minutes of Heartstopper Forever — which is the equivalent of about 4.5 standard episodes — I stand corrected. As Nick, Charlie, and the gang all brace before going their separate ways to university, a feature film actually reflects their growing maturity and crises of confidence much more fittingly. Newsflash, people: Nick and Charlie aren't kids anymore. In fact, the new Netflix movie wastes little time reminding fans of that, with a significant increase in drinking, partying and all-out sex scenes. Tender and wholesome romance can have an incredibly passionate side, too.As a Heartstopper fan who has been in the trenches since the release of Oseman's first novel installment, Heartstopper Forever feels like the most satisfying ending that's able to be delivered. Nobody really wants to be in this position, but all of my questions are answered, and every single character is set up for their future away from our prying eyes. Heartstopper Forever delivers everything a hardcore fan will wantYou're going to have to trust my (excellent) judgement on the above statement, because there's no way I'm divulging anything even faintly resembling a spoiler in this review. As we know, Nick is getting ready to leave for university, and Charlie is taking on new responsibilities at school.Elle (Yasmin Finney) has her mind set on big artistic goals, which means her relationship with Tao (William Gao) also hits its snags. More than any other characters' storylines, both relationships hit on the central theme of worth: does teenage romance even mean that much anyway?As the push-pull effect of university and a daunting, vague future takes hold, Nick falls apart at the seams. Unlike Charlie, who has always been able to effectively communicate how he's feeling, Nick doesn't know how to describe what's going on in his head. It has the pair doubting the validity of their love and connection, even though nothing is overly wrong from an objective point of view.It should be frustrating to watch two teenage boys self-sabotage, but the reality is overwhelmingly poignant. Even though the movie is called Heartstopper Forever, nothing in life is guaranteed — and I, for one, am fed up with pretending that doesn't keep everyone up at night. As Tao points out, everyone has assumed up until this point that Nick and Charlie are a "perfect couple," and it's fascinating to watch how they deal with actual grown-up problems. Oseman has always had a unique knack for conveying the best of what love has to offer, and she's just as adept at holding a mirror up to the worst. On top of this, watching the boys get physically intimate, drunk, and accosted by topless men wearing leather chaps at the local gay club feels like emotional whiplash in itself. Socially, we seem to have a difficult time understanding that young people grow up to do adult things, and Oseman handles these changes with touching sensitivity. There are some fans out there who have been waiting on tenterhooks for these moments... and the reality is spot-on. Anna Maxwell Martin, I love you... but Olivia Colman was the better Sarah Nelson(Image credit: Netflix)So we can tick off the fact that none of our favorite characters are left hanging, and we know exactly what's happening with them and where they're going. Fantastic. However, there are a few minor misdemeanors that need addressing.The main thorn in Heartstopper Forever's side the recast role of Sarah, Nick's mum. I feel like an absolute heathen even bringing this up, seeing new Sarah, Anna Maxwell Martin, is one of my favorite actors in the country. But when you remember that you once had Olivia Colman in the same role — and that she delivered one of the best scenes in Heartstopper's history thanks to Nick coming out — well, there's a somewhat sour taste.Heartstopper Forever is the most narratively and tonally different installment of Nick and Charlie's story to date, but it is still essentially more of the same at its core. Don't get me wrong, this isn't necessarily a negative... but if you've come to the movie looking for something new, you're not going to obviously find it. Still, Oseman should give herself the biggest paycheck possible for what she's been able to achieve. It's not easy to deliver a finale that already looks nothing like what everyone expects it to, let alone make the final result compelling, endearing, and ultimately remarkably satisfying.Heartstopper Forever really is forever... at least, it is in my house, where I'll be replaying it so much that Netflix might issue a warning. Its spirit and generation-defining impact will live on, and that might be the most special achievement the streamer has ever been responsible for.
