Copycat
You may call it "influence" but in my opinion, some specific shots/scenes were almost a copy of an idea from elephant, lolita (the new version), lilja 4-ever and a little bit from the virgin suicides, but especially lolita and lilja 4-ever and I guess a bit more of some current indie films.
Now, don't get me wrong - I liked the film. I though the end was way too dramatic, but maybe it's just me. Adele was gorgeous and made my stomach hurt (and I'm a straight girl), but I didn't like the fact that several shots and scenes were copied. It pissed me off.
