We went and saw it in 3D, it was a lot of fun. Great movie for kids, good movie for adults. Lots of good humor.
Only issue I had was it sounded and looked like Shrek in the beginning which really put me off. Thankfully about 10 minutes in the story picked up and it wasn't as distracting. A couple of other people there commented on that when we were walking out, gotta love the south and my-conversation-is-your-conversation friendliness.
I do like shrek, but I think this movie deserved it's own moment.
Gerard Butler is one of the voices... so yea. It's a bunch of scottish vikings. lol.
