I just rewatched this movie 32 years later after it has been shoot, and I must say, it has aged well, meaning, it is still funny and hilarious to watch. Okay, some scenes need some explanation to younger generation (like the opening Beirut scene is not really comprehensible to someone who was born in the nineties). But overall the jokes are delivered with a good timing and a still good hit/miss ratio. So, given that age of that movie, and how comparable movies have not aged as well, I am now increasing my rating from 7/10 to 9/10.
