This film makes a tremendous amateur blunder from from the very beginning: it assumes the audience has seen (what I understand to be) the first film. (I hadn't.) There is no build-up, no dramatic lead-in, no preparing the viewer for what is about to happen... no indication there even WAS a prior film. In the first 60 seconds this drops cataclysm right into our laps with no preparation, no explanation, no warning. BAM! Here's an earthquake. BAM! Here's a tidal wave! BAM! Here's a volcano blowing its top.
Same holds true for the characters. There are no references to the prior film, no flashbacks to explain the existing story, nothing to prepare the audience for characters that pop out of nowhere and we're just supposed to magically understand their backgrounds and issues and empathize with what's going on.
The result: I paused this turkey after 15 minutes of ridiculously bad directing, came to IMDB and read the reviews, then shut it off... glad that I didn't waste three hours on what I'd already figured to be a prime example of how not to make a movie. Thanks IMDB, for helping me not turn that loser 15 minutes into a total loser evening.
