This was great as far as action goes - full of non-stop running and jumping and explosions. However, language and some scenes were added for no apparent reason - I'm thinking of the dogs mostly, and the incident with Wheelie and Megan's leg. I took my son and daughter to see it and wish that I had waited for the DVD so I could skip past those parts.
As far as action goes, it was great. The gratuitous dog scenes just really skewed this movie to an older kid demographic, as opposed to the first movie.
