Kinda... I mean, there's a considerable amount of negative continuity... and a lot of fans even wonder if 3 even happened at all, let alone how it ended. Of course, some of them even think that 1 didn't happen, due to the fact that in 2, your characters go to the past to defeat their main enemy... the same enemy who was the main enemy in 1... which may not have happened anymore thanks to time travel.
