Favorite Character: Data - I can't say I always loved his development, but when done right, it was some of the best they ever did. He's why I got invested in the show, & very little over 7 years changed that, with the exception of the awesomeness of Patrick Stewart. Troi, Wesley, Worf. They were ALL gimmicks
Least Favorite Character: Lwaxana - It was as if someone thought "Do you know what this show needs more of? Obnoxiousness"...................

.................. Wrong
Favorite Episode: (It really alternates) But all in all, probably
Chain of Command. Once you get past the rather absurd notion that there's only one guy in all Starfleet who can head this covert mission, tagging along a Klingon & a doctor, it really is an episode with so much to sink your teeth into, & with screen
crushing performances everywhere you turn, even including Frakes, who's character I come down hard on, but whose performance was pitch perfect. It may be one of the most perfectly executed episodes they ever did. Everything you see there they did for a reason, & there's not a bad performance in the bunch. It's had people debating it ever since
Least Favorite Episode:
Imaginary Friend, which answers the question
... How do you spell "Nobody gives a crap"?
