Did you know that there is more than just the Lilo and Stitch movie? There is a sequel and another movie about another one of the experiments. Also there is a tv series. I have seen them all and the tv series is definitely worth watching.
Lilo and Stitch 2. People usually haven't heard about the second Lilo and Stitch movie but it is really good. It is about Stitch having a glitch that affects his behavior. It shows how he was misunderstood and how they try to fix the glitch.
