Oh wow. Did not expect to see two votes for Halloween II '81. Or 5. They're two of my favorite sequels.
That said. I just watched Halloween II again, and I do agree that it's a bit dull. I love it, but... man, its pacing is ROUGH! Used to be my favorite Halloween. Now, it may have dropped 3 spots! Count 'em, 3! Right behind III, V and I. But I'm not sure. The murder scenes are great, but I... just... want... it... to... move! I feel like Jamie when watching it at times. Aesthetics are great though. But yeah... wow... it's not my favorite anymore.
