How bad is it? It's a formulaic, predictable and unneeded sequel to a bad film.
Should you see it? No.
[You may be wondering how this and "Cop and 1/2," well-known films, got on this blog. I'm starting to wonder, too.]
Sony apparently saw money to be made in a franchise starting with "Daddy Day Care," prompting this sequel, which has Cuba Gooding Jr. subbing for Eddie Murphy and directed by first-timer former child actor Fred Savage. There's a run-down camp in competition with another and some father-son relationship plot points, but mostly it's fart jokes and bodily fluids. It's woefully unfunny. I saw that there were some people giving this high praise, but it appears that it was an attempt to get a higher average rating, whether by people involved with the film or (more probably) some trying to get their pet bad films to the bottom of the rankings.
