Biggest problem with the first VOY relaunch is that they kinda forgot to give it a reason to exist. Wasn't really anything going on, they broke up the crew a bit, and just had a generic series wandering the AQ, except this one had "voyager" stamped on the hull.
How was that a "Big" problem? TNG & DS9 showed the crew splitting up on screen, so why would that be a "Big" problem for Voyager? Really, would you expect Starfleet to not reassign people, even though they've been together for 7 years on screen.
