I particularly like TNG and VOY.
As a matter of fact, I've been watching TNG for over a week, currently in the last season :)

I do not like DS9, ENT.
Picard... I find it difficult to watch him being so old.

The TOS was great, but to watch that now... the effects, computers, etc. are so obsolete! And much of the script very childish now. It does show how we have grown and changed!
Watching a young William Shatner is certainly no crime though

I also love TNG movies and the ones with Chris Pine as Kirk.
I rewatch them quite regularly, but never the older movies.

I especially love episodes/movie about the Borg! It was great to introduce an entirely new enemy race.
