Go for it. I did it recently, and I was ready to give up by the middle of season 7. I didn't realise how mediocre the last season is until watching it four episodes at a time.
I own all the seasons but have been unable to watch anything past the middle of Season 7 since it aired.
Agreed. I have seen very little past mid Season-7 since first airing. The only exceptions are "Endgame" and "Author, Author" I think, and even those were a while ago. And I won't really watch "Endgame' anymore.
Season 7 is a barren wasteland for the true Janeway-aholic; this is quite true!
