There is a reason why this is the absolute worst film of the 90's
Reason one.
This film was super hyped. At every commercial break this film was compares to being better than aliens and better than the terminator. This advertisement misled the american populace. In 1990, people still had faith that hollywood was going to ddeliver summer blockbusters. Then they rolled this baked turkey out and almost completely destoryed the last one hundred years of film making (terminator 2 restored people's faith).
The second reason this film is bad is that it's the script and everything else in it is all out of pace with the rest of the film.
