A shift in outlook is neccesary to enjoy modern British films, one that somehow allows them to be seen in their own right and for their own qualities rather than by the criteria that American films are judged. Britfilm has to try hard to be gritty and finds it hard to make it, but at warmth British films can lord it over their otherwise overwhelming competitor.
This film fails not in its content but only in attaching itself to the predeccesor, so allowing it to be all to easily seen as the work of star and director somewhere near the end of their tethers. It's a couple of decades later, Gregory teaching and this time with two girls on his mind. He teaches at his school railing against human rights abuses. When students he's fired up find abuses in their midst he must face whether he's just all talk.
This is a subversive film in that there's not the usual worldly character of any American movie that you expect to do whatever he does, but a naive man boy who may still put everything on the line for principles. Maybe. It's certainly no protest-by-numbers though, being too warm. Where U.S. film may seem realistic because they're urban and gritty, this and other British films of recent years - those that don't try to match America for visceral thrills - are real because British humour reveals truths.

Witty. Quirky. Genuine. Surreal. Butterfly wings? One could ask what all of these words best describe, and some (those in fuse with the international film community) may quickly say Happenstance, but others may jump aboard the more American train and immediately yell, The Butterfly Effect. Strangely, I would be one of those screaming for that sci-fi Kutcher film mainly because none of those words that I initially mentioned at the start of this paragraph accurately depicts the Tautou feature that I witnessed. Sure, we all loved her in Amelie and thought she was the daughter of Jesus in The Da Vinci Code, but in this film first-time director (of a feature film at least) Laurent Firode doesn't give Tautou the opportunity to shine. Sadly, he gives nobody the opportunity to really demonstrate themselves because he is too delicately caught up in the moments of "random chance" to bring this film to anything but just a shimmer (never a true boil). Firode has ample, and I use "ample" as a small word, moments throughout this film where he could have built us a fantastical story, a genuinely whimsical fairy-tale of love and coincidence, but instead he fell face-first into a mud-bucket of chaotic intertwining that overwhelmed us with inconsistent characters and a story that left us gasping for less.
Tautou's beautiful face adorns the cover of this box, but do not be so taken immediately as I did in assuming that this was going to be another monumental journey into Tautou's French cinema. Tautou is in this film, do not get me wrong, but one could argue that she is not at the center of this story. Firode's job is to create a series of random events that eventually will lead to an audience friendly (albeit confusing) ending which exemplifies that meaning of refreshing "melodrama". He utterly, utterly fails. Firode fails by giving us, the audience, too many characters. With too many characters he gives us too many random interventions, and by the end you don't really care who is who, or what is what, or how is how; your main focus happens to be centered solely on the ending credits and the time destination of their arrival. Tautou could have saved this film from the disaster it was if only Firode would have given her the center. Alas, he did not, but attempted to seemingly force a group of 12 through a theoretical film hole about the size of a penny. It just didn't work and we were left with a jam in which we were completely stuck.
Firode fails because he focus' so intently on the minor details that, for one of those rare film occurrences, he actually forgets the central focus. I can say that there was no defined central focus to Happenstance. In the beginning he attempts to create one with our two supposed main characters discovering that they share the same birthday and their horoscope promises love by the moonlight, but we never go back to that throughout the film. Instead, again, we are bombarded with new characters, stuffy scenes, and meaningless drivel obviously chosen to direct us away from an actual story and more into a world full of "ifs, ands, and buts". I couldn't do it. I couldn't believe this film. Writer Firode (yes, the same guy directing this garbage) uses a technique so primitive in this film that I immediately felt like ending it immediately. He must have been assuming that many of us were incapable of actually following the storyline (or the scientific premise) because he grabs the aid of a homeless person to actually fill in the respective blanks. I didn't need this, nor do I think Firode needed to belittle his audience in this matter. While there were other elements that just didn't seem to work for me at all (again, felt like a jumbled Parisian collage of shredded paper), this was the icing on the cake. I don't need my hand held through films.
I will give this film one star for credit. This is a rather difficult genre to master successfully. Time travel films are especially hard because of the innumerable amounts of possibilities that are never accounted for, but with Happenstance it works because Firode semi-explores the different avenues. While I will counter with saying that he does not do it well, it did make for at least five full minutes of enjoyment. I liked where Firode was headed with this film, he had a genuinely diagramed story, but the final execution just blew this film to shreds. Firode could have saved this film if he would have strengthened his characters, while lightening up his premise and story. I think my overall mood of this film would have changed if just these two simple directions were taken. Oh, how I only wish I could time travel back to the production of this film to show Firode the errors of his ways.
Overall, for the first time (and probably last), this was a Tautou film that I must say utterly disappointed me. From the choppy opening to the apathetic ending, I just felt that Happenstance failed due to Firode's leadership and horrid marketing. Marketing is something that I didn't mention before, but why would anyone purchase this film thinking that it was an Amelie 2 (per the title released in Hong Kong), and why would you place Tautou squarely on the cover knowing full well that she wasn't carrying this film at all. I believe that from the first minute that passed on my DVD player, this film was in shambles. While I will applaud his subject, everything else was well below the level of mediocrity. I cannot suggest this film to anyone.
