I've always loved this movie so much! The love Bolt has for Penny is outmatched by any dog character I've seen in any other animated movie like Bolt. Nothing really bad to say about it, but I do have some things I wished happened in the movie.
1: Dr. Calico making more appearances. He only made like what, 2, 3 appearances, then never showed up again until the end.
2: Rhino never showing up. I get it, they wanted to add the "Biggest Fan" character, but I kind of wished Rhino either never appeared, or just showed for one or two scenes like the Hollywood pigeons.
3: Maybe some more scenes with Bolt jumping out of moving vehicles. I found that pretty funny for some reason. "You should stop jumping off trucks doing 80 on the interstate!"
4: The Agent. I hate that guy. I know he's the main antagonist of Bolt, but they could've made him more passive, and not the "Let's put a pin in it" guy.
