Yes, the humor at times was sophomoric. I have not seen the original version, so I can't compare the two. The movie has little in the way of plot, just people at a funeral addressing odd issues as they arise. Chris Rock places the "straight man" and is our voice of reason.
Martin Lawrence, plays his brother, who is a published author. He pretends to have a lot of money, but is broke. He spends his time at the funeral attempting to pick up the hot 18 year old neighbor girl. He asks her to NYC and says, "I got all kinds of snacks. Like Sugar Daddies?" Chris' mother laments about not having any grandchildren in front of Chris' spouse who wants sex every day. During the funeral she says, "We got 5 minutes, I'm not wearing any panties."
Danny Glover plays the curmudgeon uncle in a wheel chair. In one scene he proclaims, " I know a dead man when I see one. I live in a retirement home." The cousin has a white male boyfriend who is high, but not his fault. She tells her dad he is on Valium. Dad replies, "Your mother was on Valium for 30 years and she never knocked over a coffin." Meanwhile, her ex-boyfriend is also at the funeral and is trying to rekindle their romance. He laments, "I've only been sleeping 8 hours at a night. I am at my wit's end."
If you enjoy that type of humor, plus a little slap stick, you will enjoy this somewhat low-brow production as much as I did.
