I think it's a tough market. Making adventures and action movies you aim at a big audience. Comedies are diffocult as people have different sense of humor. Imo it's not just a last decade, I find them tough to find generally.
I loved Zohan, dislike almost everything Sandler touches, but that one was great, the 5.5/10 on IMDB doesn't do it justice Also love Will Ferrells Semi-Pro (with Woody Harrelson)
