One of my (many) problems with TNG was I never gave a rats for any of the characters. Okay I admire Picard and First Contact is still one of my favorite all time films.. but the rest of them just bored me to death.
Data=BIGYAWN.
Deanna=PLEASE stop talking!!
Geordie=Who?
Crusher=Nice Hair
ENT, I've enjoyed the characters who got airtime immensely. T'Pol is a fascinatingly flawed Vulcan I never tire of.
Phlox, well I just watched Regeneration and his acting was great in that, his sheer helpless terror as he gets into the medical tube to try and destroy the nanoprobles ravaging him. Lots of background on Denobulans, some personal things about Phlox's family, seeing one of his wives, his ever-dapper personality..
Reed was a great character too, his work devotion and negativity and introverted ways.. he was very realistic.
And Trip.. well as the series moves forward he becomes a very interesting character indeed.
Each rewatching of ENT renews my appreciation of it. I think the whole "first time out this far, hot damn a discovery!" and their unfamiliarity with how to approach some things was very well done. I think they achieved that feeling they wanted to convey in the first two seasons.
Plus the whole series looks GREAT. Very sharp. I love the greyness of the ship. I love the jumpsuits, I think they did a great job moving away from the TNG-Hilton criticisms.
