I was upset when I first watched the 14th movie. Sure, I definitely enjoyed it, being the lbt fan that I am, but I don't see why they didn't add in the rest of the gang. Chomper and Ruby just stayed with the grown ups, which was awkward to watch.
I do see some reasons on why they had left them out. Having to draw lots of characters in one scene can be a struggle at times, and I guess they considered that pretty well when they were story boarding the movie.
