There were a few discrepancies with the prequel that made some of the events in the first film null and void. Continuity issues abound, but Ginger Snaps Back is a film that gets better with subsequent viewings (like he original Day of the Dead) You have to admit that the werewolves looked better than the creature Ginger Fitzgerald eventually became in the original. Other than that, if you can get past all those things, it's not such a bad film and could even be a pretty decent companion piece to another great Horror movie based on that era, Ravenous.
