Predator 2 has always gotten flak not because it's such a bad movie, but because it's just nowhere near as awesome as the original. It's also never helped that the Alien and Terminator franchises both
did have second entries that were as awesome as the first. We were treated to Aliens and Terminator 2, which exceeded all expectations... and then there was Predator 2. It's certainly watchable and somewhat enjoyable, but it's certainly not something that anyone comes back to watch again and again, dozens of times throughout their life, like Predator, Aliens and Terminator 2.
This was the worst predator movie, worse than the avp movies.
I find it awfully hard to believe that it's worse than AvP: Requiem. All that they needed to do was light the predator just enough so that we could tell what it is and it would be instantly better.
