I liked, TOS watching it in reruns in the 80s. TNG was pretty good, it was a cool thing to watch as a family when I was a kid. DS9 I watched most of, but was doing a lot of other things in life while it was on, so missed a lot of episodes. Voyager, I was enjoying until the year of hell where everything was reset. Lost interest after that, but ST time travel has never been my favorite thing, as a general rule, any of the time travel episodes of any of the series were usually my least favorite. I tried watching Enterprise in its initial run, but could not get into it, however I did just binge watch all 4 seasons and enjoyed it pretty well. I still think Tucker and T'pol should have had a kid the natural way. I have watched all of discovery so far, and really don't care for it. Strange New Worlds I am enjoying, Picard, I could take or leave, it has a few good episodes and a lot of dumb ones. I thought I would hate Lower Decks, but actually find it hilarious most of the time. And loved the LD/SNW crossover. Prodigy is really geared for kids, it is ok, but not a huge fan.
The movies with the original cast were mostly good with Wrath of Khan my favorite and the voyage home questionable. The movies with the TNG crew were OK mostly. The Reboot movies I enjoyed, but I mostly disconnected them from TOS.
