Rosie and Alex have been best friends since primary school. They nearly got romantic on Rosie's 18th birthday, but Rosie was way too drunk. Since then, both have had relationships, just not with each other - timing has always worked against them.

When I watched the trailer for Love, Rosie, I thought "I now know exactly what will happen in this film." But I like Lily Collins, so I went to see it anyway. And I was quite right - the story progresses along the tramlines which are displayed in that trailer (with one or two little sidetracks), so don't expect any earth-shattering surprises.

But it doesn't matter. Lily Collins and Sam Claflin have an easy chemistry, the film is a romantic drama with some gently amusing moments, the supporting cast is good, and Collins turns out to be able to do a bit of acting, too.

I enjoyed this.

There is a lot to like in Love, Rosie including appealing leads who are wonderfully photographed but this is a sub par Four Weddings and a Funeral.

Rosie Dunne (Lily Collins) and Alex Stewart (Sam Claflin) have been childhood friends who are meant to be with each other. However Rosie gets pregnant after a one night stand, Alex goes off to Boston to study at Harvard and she does not want to stand in his way. Eventually Alex gets engaged over there and Rosie marries the father to her child.

Throughout the film you just want the two main characters to properly talk to each other to clear up any misunderstandings. Instead the film dreams up further silly contrivances to keep Rosie and Alex from hooking up to each other. So they repeatedly have a dalliance with people who are second best.

This is an energetic rom-com, amiable enough to watch but it never rises above average.
