Tough call here. I have a hard time viewing this movie objectively due to the affection I feel for having seen it in the theaters as a kid.
It’s not great, definitely far from it, and deeply flawed. Mostly it coasts on the chemistry of Dan Aykroyd and John Belushi both playing against type as unlikely neighbors thrust together at the end of a remote cul-de-sac… Aykroyd as a wild man and Belushi as a conservative, but both with the comic chops to pull off what otherwise might have been a disaster on the order of casting Steve Martin as the straight man in “Planes, Trains, and Automobiles”.
The writing is terrible though. I like the film in spite of it, but, the writing is pretty terrible.
