I'm a voyager fanboy since it aired, but it really doesn't hold up well.
Nevermind the fact that it is low quality visually and will never be remastered, but the practically non existint continuity really really really hurts it.
I still recommend people watch it, but it would be 3rd of the 'old' shows I'd suggest. (DS9 1st always because it is fucking awesome, then TNG because it brought Star Trek to the masses and solidified a lot of 'canon')
The arm swing is such a subtle thing he does, yet it really sells that he's an alien who's built different than a human (or most other humanoid aliens in trek which are too human like)
And that ending. It was both a let down for various reasons and rather fucked up too for what they did with Zora (I guess to tie into Calypso or just get rid of the spore drive?)
To me I'm gonna miss the potential this show had more than the actual show we got.
