Took Sergei to see it the other day. We both really liked it, though at 5 he didn't do a great job keeping the glasses on. We did not get to keep the glasses. We went to the Marcus in Pickerington.
As for the movie, I thought it was a nice use of the book and not something they used too often as a crutch. I also liked they included som YoYo bits since I feel they should be in all 3-D movies by law.

I thought the cast had a nice dynamic, and while it was predicitable to a great extent, it was a nice fun summer movie.
I also liked the bit early on where Trevor was going through Max's stuff and pulls out the stereoscope and has no idea what it is. A nice little wink to those who love 3-D.
