Dragonslayer - One of Disney studio's attempts at the adult market, and not a very successful one at that. The dragon is certainly well-done, but the story is slow and disorganized, and while there are excellent scenes interspersed with the rest, it just isn't worth the wait. Dune - I'm not a fan of the novel, so maybe I'm biased. In any event, I found this movie boring and pointless. Things moved too slowly, and without apparent motivation.
Various actors overact their faces off to no real gain.
