I was a third of the way through and decided to just skip to the end. This family is unlikable and pushy. I don't know how he changes as a character, but I was on the uncle's side a third of the way through. The mom's whispery baby voice is annoying. Not only was she and her kids annoying, but the mom decides to bring an extra kid in, a stranger, when it looks like they can barely make ends meet at a junkyard. Also, having skipped to the end while watching this, it's very anticlimactic.
Also, I got Orphan a bit in some aspects. Reading other reviews after the fact, I see other people noticed it too. Once the I saw the teeth thing and then jumped to the end where she's wearing makeup, it clicked (maybe there was more in the middle too). But whereas the actors and characters in Orphan were done rather well, with strong performances from everyone, even the children (but especially Vera), I couldn't care less about this family. Don't rip something off unless you're going to do it better or as good. At least they didn't make a carbon copy, but it's still not better or even on par.
At least Jackson Rathbone actually emotes in this. But seeing him in this lets me know he didn't improve as an actor since then. Also, he has awful hair in this.
