This review will probably offend you...
Because I'm not going to follow the rest of the sheep and hang off your every word while literally sucking on your ballsack. With that said, let's begin...
First off, I do not understand why you thought this would be a good story. The animation begins with the cliche of a kid doing whatever he wants then realizing it is not as good as it first seemed. The second half of the film is just two people at odds with each other who eventually realize they have feelings for each other. Probably sexual feelings...
Where is the character development? Where is the buildup towards realizing that the kid and the grandpa aren't a bad fit together? Since when has someone ever been punched and said "Hey, this annoying brat is all right with me,"? Oh, and by the way, you made a poor choice in who to focus on as a main character here. Who the hell wants to watch a kid that does nothing but be a dick (if someone does, however, then they probably need to get laid)?
Finally, I want to ask the following: how many years have you been making these movies? A few, right? And yet, nothing has changed. While your first few movies were good, you continue to ride the coattails of your early success and fail to escalate as you go on. It's a tragedy, to be honest.
Basic summary of this review: this is the third matrix movie.
