This fourth installment in the *'Lilo & Stitch'* series feels rather unnecessary. Although it’s not completely awful, *'Leroy & Stitch'* doesn’t really offer anything worthwhile. The story seems disjointed, and the new characters don't manage to spark any interest. I was glad to see a continuation of the events from *'Stitch! The Movie,'* at least. The voice acting is generally good; it’s nice to hear Daveigh Chase reprise her role as Lilo, and Jeff Bennett and Rob Paulsen are solid in their performances as Dr. Hämsterviel and Reuben. Most of the other actors, including Tia Carrere (Nani), have less to do. It seemed inevitable that they would produce a film that wasn’t great at some point, but I'm relieved that none of them have been truly dreadful.
