There are too many glitches in this movie to easily overlook. There are a lot cute moments but the story line isn't as powerful as Finding Nemo's. After 13 years this movie is released and you wish for something awesome to happen but it doesn't.
Moreover, they felt this god awful need to explain and justify each and every element from the first movie in this sequel. For example, why dory sings "just keep swimming" and also why she thinks she speaks "whale." What I'm saying is they've tried really hard to connect everything. But it just didn't work that well.
The film is not an ideal sequel of an otherwise one of the most epic films of all times that required 3 years to be constructed that awesomely. However, nonetheless, it is a one time watch.
