Review of Rev

I really enjoyed this film, i know you kinda know what's going to happen .... guy falls for bad guys girl & all that however , i loved it! I'm a fan on gone in 60 seconds & it's kinda along those lines. I'm no film critic I just really enjoyed it apart from one thing. End of the film yep leaves it open for another one at some point but, I can't get my head round Charlie & Ava & Mikey. Is it kinda they both get the girl in the end? The girl gets to have her cake & then some? They could be happy like many others with all three of them in a relationship? Don't know but it's confused me & I'm irritated I don't know. These details don't need to be made clear in the film ....... I just need to know! I know they are acting & this is not 'real' just my fricking weird wanting answers.
