I think I have seen every example of the "body switch" genre, at least all of those that have been made in the past 40 years or so, and "Like Father Like Son" is the worst of them. The first 20 minutes or so are painless mediocrity, but then soon after the movie collapses. What's the problem? I think the main problem is that the characters are stupid. If I was in their situation, I know I would be terrified and trying my best to not raise suspicion. If the movie had done that, it could have been funny seeing these people trying to do their best but making mistakes. But the movie's two main characters seem to be trying their best to blow the charade - not realistic. And the movie's sense of humor is really bad - we have such stuff as audiences falling asleep during lectures, a gag that's done TWICE. If you want to see a good example of this genre, see "Freaky Friday" (the original or the remake) or "Vice Versa".

Im not too sure about what the last reviewer was expecting to see...Citizen Kane? This was a great lighthearted comedy from the time I was graduating high school that anyone born in the late 60s-early 70's will enjoy. You will love the cornball fashion from the big 80's as well as the big hair. I thought they put a interesting plot in the freaky Friday theme using the brain transference juice. Also, Dudley Moore did an excellent job right after the switch acting like a freaked out 17 year old in a 47 year old's body. And of course, the comedy ensues as both struggle to jump into the others life, one in high school and the other at the hospital as chief surgeon. So if you want to come home and have a drink and relax and watch a lighthearted comedy from when you were in high school and remember the old days, this is definitely the movie for you.

The jokes did not quite take off in the first half of the film. I was appalled by how bad the dialogue was, and how un-funny the lines that are supposed to be funny are. Chris' best friend is perhaps THE most annoying person in the first half; his lines are retarded, and so is he. Chris (Kirk Cameron) is also very annoying, and so is his dad. After they switched brains though, the film got a whole lot better. It's a riot to see Dr. Hammond in Chris' body going to school and being a smart ass. It's even funnier to see Chris in his father's body going to work. This movie is basically something to entertain you for a couple of hours. It's not over-the-top-ly funny, and it's very stupid, but it's all in the name of entertainment. Great acting from Dudley Moore and Kirk Cameron. Can't say much for the rest of the cast 'cause I don't really remember what the heck they did. A rather interesting plot as well, if you're not in the mood to think.To sum it up, "Like Father, Like Son" is stupid...but it's fun.

I could fill pages on why this film is such a pathetic attempt at the "kid/parent" switch comedies of the 80's but let me just give you a quick summary.This film completely fails to portray how people put into this situation would behave. The best (worst) example of this is the scene when Dudley Moore, playing an 18 year old in a 40 something body, is staying at home alone. He's supposed to be a senior in High School and yet when left at home for 5 minutes he behaves like a 6 year old....playing loud music and jumping on the furniture. Obviously the director just couldn't resist having Dudley Moore jump around like an idiot for a few minutes.Had the writer and director spent 30 seconds thinking about how people might really try to act in this situation it might have been entertaining...but then again this movie was made about 5 times in the space of 18 months in the late 80's anyway so I think the best idea would have been to get an original idea and not waste everybody's time.
