I think Caddyshack is crazy overrated. Stripes has very funny scenes but fails as an overall movie (especially the last act which is just boring).
Vacation is funny, screw you guys.
It may be funny to some, but I truly loath Chevy Chase and can’t get past that.
The only movie I like that he is in is “Last Action Hero”, where he plays himself in a very brief cameo role.
When I was 11 years old I thought “Foul Play” was a riot. The when I saw it again 15 years later, I was shocked at how bad it was. You can also include any “Hit” movie with Dudley Moore on my list, such as “Arthur” and “10”.
