I saw this on Sunday.
The important thing to realize is that the movie is more of a 'dark continuation' than a remake. If you're expecting a happy Alice tale, that isn't what you're going to get... It takes place when Alice is twenty and Wonderland isn't very happy any longer.
There were some scenes that made me cringe, mostly (spoilers here)
the stabbing out of eye theme throughout the movie and there is a scene where a miniature Alice is jumping across the moat using the heads of the Red Queen's victims as stepping stones.
It's hard to make me cringe, I didn't have trouble with Saving Private Ryan...but perhaps the issue was simply that I wasn't expecting it in a movie like this.
I loved it, though.
Christopher Lee as the Jabberwocky was a wonderful treat.
