TNG cast all day for me. I'd take Picard, Data, Riker, Troi, Crusher, Geordi and Worf over the others. Best cast in total by far. I like Janeway and Sisko mainly from the other two, but their supporting casts came up short to me. Enterprise was kind of a shoe horn to me and felt a little odd, but was still solid.FTFY.
Kidding aside, I've only ever liked TOS and the TOS-related movies. I've tried TNG and I just can't get into it. TOS was fun pulp with some heart. The rest is too reddit for me. It's far too divorced from my tastes and it comes off as pretentious and hollow to me. I like the JJ flicks for what they are, but they're Trek in name only so I get why proper fans don't like them. I want Kirk & Spock dollies on my shelf, but with so much on my plate from HT, it'll be hard to swing Exo-6's figures, especially if they come out soon. With HT I can put them on installments and pay them off in 1.5 years. Exo-6 puts them out too fast, which is great, especially with how good they are quality-wise, but they're not carried by any stores near me so I have to factor shipping and taxes and it's a nightmare.
Anyway, I'd watch a 4th flick as I like the cast.
I am glad someone like EXO is banging out Trek stuff, but the Picard and Janeway sculpts just are not there for me. We will see on the incoming Sisko. Data was pretty good.
