Saw this one in 3D. First thing you should know: there's no reason to pay the extra money for the 3D version as pretty much the coolest 3D stuff I saw that day (saw it last Saturday afternoon) was on the trailer of the new Transformers movie. Second thing you should know: I'm not familiar at all with the book or with any of the other movies. Maybe that's why I'm one of the few ones here in IMDb who gave more than 4 stars to this movie.
Anyway, there's really nothing amazing going on here. The story is as predictable as you can imagine and well, Jack Black is yet again playing Jack Black. We all knew this, and frankly I don't think there's a person who can't tell how is this movie going to be like before seeing it.
I knew, and went to see it anyways as it was pretty much *the* movie of 2010's Christmas. I mean, I'm a sucker for Jack Black movies and even though the trailer never really convinced me, I had to check it out. Maybe The School of Rock and the Tenacious D movie (big fan of both) were more than enough for the punk rock Jack Black but it seems is inevitable to have him "rocking". So here some references to Guitar Hero and KISS are present. Jack Black is put as a sucker for rock music and movies, Star Wars especially. That simple thing delivers the best moments of the movie: Gulliver making the Lilliputians act Stars Wars and Titanic and perform as KISS. It ain't pop culture references heaven but definitely delivers the goods (also some Avatar references were funny).
Gulliver's Travels may not be Jack Black's funniest movie, but in the end it was just what I expected: a decent family entertainment that will be soon forgotten but that is enjoyable to watch.
