Personally, the first movie was not bad, followed by the second one, which was alright I guess. But then when the trailer for the third movie came out, boy, I could tell ya how much I cringed at it!
I could already tell that this was too much, and a very lazy idea to plot out a movie. Unfortunately, my parents put the movie up in our living room, and I only glanced at it for a few moments. The 'jokes' weren't funny, to kids maybe, but it was just so hard to see it play out. They were trying too hard, and as an individual who is studying under computer animation and a story boarder, I feel sorry for the people who had to sit down and make this.
It is a family movie after all, I'm sure the children will enjoy it. But It just seemed unnecessary to make another one of these. No one asked for them. If you're going to make a sequel, for god's sake, please put more effort.
Again, this is just my opinion.
