While no one could accuse the film of narrative complexity, this is nonetheless an example of Raimi at his most playful & visually creative. Blending elements of A Connecticut Yankee in King Arthur's Court with Three Stooges style slapstick comedy, Ray Harryhausen inspired stop-motion battle sequences & his own 'deadite' mythology, the film offers a veritable cornucopia of amusing post-modern invention.
It's rather pandering material in its juvenile comedy and teenage-esque, smartass wisecracks. The serious tone of the first, and the dark-humored tone of the second, is forsaken for Three Stooges-style humor. Even when watching it as a parody of itself, there is a feeling that it had to be a easier-taken opiate for the masses, when I wish it was as repulsive for them as heroin. That said, I still laughed enough.
For me this was the best of the 3 movies. The first one was genuinely scary. The second one was the same as the first, but with more humor. This was more my style with less overall violence and blood, and much more humor with a lot of the same elements. "First you wanna kill me, now you wanna kiss me. Blow."
Raimi's third in 'The Evil Dead' series always seemed a compromised affair that failed to provide any of the horror the first two entries contained relying more on its comedic elements. It's a fun film however especially with its traditional mix of effects that stand in tribute to Ray Harryhausen.
7 - "Evil Dead" meets "Monty Python". Many would argue that at this point the series became a full-blown parody of itself, and I'd agree, with the addendum that it absolutely succeeded in that endeavor. "Army of Darkness" is both the loving tribute the genre (and the decade of excess) deserves and the fitting closing chapter the series needed.
