It pains me to say this, but this felt like a throw away movie from 2 minutes in... and it never recovered.
Too much CGI and poor editing of it (parts of it felt like a TIm Burton Movie), a forgettable villain who for as clever as he is supposed to be should CLEARLY see what he's trying to accomplish isn't working, way too long of a running time, and perhaps worst of all... it's just a retread of all the same jokes we've heard before. It never gives you the feels like the first two, IMO.
Even the sound track seems forced.
Not something I'm rewatch when I decide to watch the first two, or probably the one I will continuously fall asleep watching at various points.
