There are bad movies, of course, like, say, 1985's Gymkata starring Olympic gymnast Kurt Thomas, and then there are REALLY bad movies like 1993's Leprechaun with Jennifer Aniston, but Mortal Kombat takes BAD to a whole new level, like, say, if you put a leprechaun in tights and asked him to suspend himself in still rings and then did your very best not to giggle to death. Remember, he's still wearing those brass buckled curlicue elf shoes, a hat, and smoking a pipe.
On the bright side, if you did giggle yourself to death, at least you'd have gone out laughing.
The one character who makes Mortal Kombat tolerable doesn't last very long, so, yep, that's a real killjoy. And dang, he had some KILLER one-liners!
The other characters appear to be Sears models they found in some mall, so the entire affair is just incredibly cringeworthy.
Yikes.
p.s. Speaking of bad-yet-giggleworthy cinematic disasters, you gotta check out Arye Gross in 1987's House II: The Second Story (get it?) and then 1992's House IV (3.9 on IMDB). They're so bad they're fantastic!
