I guess having expectations lowered a bit going into it is not a bad thing. I also liked the trailer but it pretty much is the entire movie. I'm quite sure I would have scored it a bit higher in case I would have gone in completely blind. This said, I'm still glad that I watched it and had an ok time with it so by all means don't let this hold you back. If you liked the trailer you pretty much know more or less what you are going to get.
