Rosie (Lily Collins) and Alex (Sam Claflin) have been friends since they were little kids. On Rosie’s eighteenth birthday, the two share a kiss, but Rosie is too drunk to remember. Thinking that Rosie simply wants to forget that it happened and remain friends, Alex moves in a new direction. Although they seem so perfect for each other, that one moment leads to years worth of missed opportunities and bad timing. Both Rosie and Alex wonder if they’ve missed their chance, which only leads to more awkward encounters.

In the rather predictable world of romantic comedies, these films must do two things very well. First, the comedy has to actually be funny. Second, the chemistry between the characters has to feel real. Love, Rosie does both of these things incredibly well, and even manages to have some more unique elements you don’t always find in the romantic comedy genre.

Normally there’s some sort of falling out between a couple that drives them apart. While that does kind of happen in Love, Rosie, it’s a surprise pregnancy that keeps Rosie and Alex apart initially. This is an interesting starting point, and one that provides plenty of room for overworked teen parent jokes. In fact, it’s the earlier parts of the film that feature the strongest comedy. This isn’t because the second half can’t hit the jokes, but because as the characters grow older, the situations become more serious. There’s still a few great laugh out loud moments, but they tend to be more successful for viewers who are parents.

The real success of Love, Rosie is the fantastic chemistry between Collins and Claflin. It’s so good that it makes some moments of the film seem ridiculous. Rosie and Alex are so obviously in love with each other that they’d have to wear signs announcing it to be any more obvious. This makes things seem very odd when you can tell that other characters see it, but say nothing, even if they’re in relationships with Rosie or Alex. Though the chemistry makes some situations rather silly, it also heightens the more emotional moments. Tears will be shed, and there won’t be a dry eye in the theatre. It’s obvious from the first moments where things will end up, but you’ll really want to see that happen, and will enjoy every moment until you get there.
