Query: Wow, what a letdown!

First, let me say I REALLY liked Pitch Black. Great movie. This sequel, on the other hand, was horrid. The graphics were pretty decent, and there was a lot of action.....however, the plot, if you could call it that was weak. Necromongers? Underverse? You have got to be kidding me. I put this in the category of sequels that should never have been made, alongside Speed 2, and Mad Max:beyond the thunderdome. All three of these were movies I enjoyed, followed by sequels that were a real letdown.
