Danny DeVito is one funny fraggle. Although seldom the lead, still his roles are oftentimes the most memorable in any film he's in. His track record is very impressive, consisting of classics such as, Batman Returns, One Flew over the Cuckoo's Nest, Ruthless People, The Virgin Suicides and It's Always Sunny in Philadelphia to name a few, yet his greatest comedic performance, is arguably the good-hearted idiot who want to kill his own mother, in the aptly titled film.
And the fact that his querulous mother is played by the perpetually sour faced Anne Ramsey, makes for a perfect character comedy, where the laughs are never far between.
So if your sense of humor tends to sway towards the bleaker side of black, you won't be disappointed by this forgotten gem.
