Are you kidding me? I loved Army of Darkness. The whole Evil Dead series is a little campy, but that's the charm of the movie. I like the combination horror/action/humor of the series. Bill Campbell as Ash is something of a poor man's Han Solo for me - lots of bravado with equal parts bravery and stupidity. He's out for himself completely, but finds himself something of a reluctant hero by the end. If nothing else, I'd watch it again just to see an army of the dead marching on the castle and for Ash's over the top acting and memorable one liners.
"That's just what we call pillow talk baby"
"All right, you primitive screw-heads, listen up! See this? This... is my boomstick!"
Bruce Campbell is one of the most under-rated actors of all time and his book is hilarious.
