I actually think Ghoulies IV
is easily the best of the franchise. After the Ghoulies start talking, it's time to pack it in- which is why the "ghoulies" in that movie were actually new versions of Grizzel and Greedigut...only they're both male and one's black. I'll never watch GIII a second time.
(Wynorski pwns. Except Transylvania Twist
is his Wicked Stepmother
and Not of This Earth
is his Full Moon High
. And I assume everything after 1993 or thereabouts is probably unwatchable... Okay, shoot me already.
