I stumbled across this film randomly when I was looking to see what exactly Rachel had done since The O.C, and I'm really glad I did.
Tom Sturridge is really exceptional in this film. It centres around two childhood friends, Emma who goes off to live her life, and Willy who can't imagine his life without Emma. Never wanting to impose on her life he simply 'goes where she goes', essentially I suppose, stalking. Tom does it with such a sweetness that it's impossible to find it creepy like it probably may sound. He's just waiting, waiting for the right time to reenter Emma's life I suppose.
I recommend it, it's a very sweet little film. It's not a hilarious rom-com, so if you're after that, then look elsewhere. It's a sweet, touching story that I'm really pleased I got to see.
