When I heard there was going to be a TITANIC 2 I instantly thought that it would be about how the iceberg that sunk the original Titanic was actually a spaceship and once it gobbled up the bodies of all the victims (and replaced them with fake corpses) it took off, but then the prisoners revolted and beat the crap out of the aliens and took over the spaceship, even going so far as to call it Titanic 2. But then the shit hit the fan when they realized they had no idea how to fly the spaceship! Soon they crashed into an asteroid and sank. All 1,517 souls perished. :-(
Instead TITANIC 2 is the extremely low-budget story about a world were damn near everything is CGI. In this CGI hellhole they make a Titanic 2 and on it's maiden voyage it's hit by a 843 mph tidal wave and all fucked up. Stuff happens, I cussed a lot, then yawned a lot. The End
The only good thing about this movie is the title. Skip it at all costs.
