TNG: Made it to the series finale, but I could not squint and pretend a number of episodes were uninspired and lifeless affairs.
ENT: I never believed TOS needed a prequel series, and as expected, the various acts of retconned BS made the series feel like some alternate universe exercise, which made tolerating the series all the way through quite impossible. Ironically enough, ENT's finest hours took place in an alternate, or more specifically mirror universe in the "In a Mirror Darkly" 2-parter.
PIC: Nope. Endless reasons why.
DISC: Same.
SNW: See ENT entry.
