"Dr. Doolittle 2" (2001)
The kind of movie you'd expect from Martin Lawrence these days, this paltry sequel is further proof Murphy doesn’t know when to quit. His only job is to let the critters deliver the punchlines. The animated movie world has more than enough talking animals—who needs them in live action? By the way, the cameo from the late Steve Irwin wasn’t funny before, and certainly isn’t now.
