Lower Decks is great Star Trek imo and a really good example of what pushing more towards a "franchise" format should look like. Instead of rehashing the same concept over and over (not that the previous trek series truly did this), set a completely new type of show in the universe. Diversification of the franchise is what works best for me.

Discovery is very alright to me. The only thing that's rough about it to me is the acting (ugh, Burnham in S3 was hard to watch), but besides that, the plots were fun, thought-provoking at times, and the show itself is visually stunning. Also still love the batch of ships we got from the first season (my eaglemoss Shenzhou has a special place in my heart). I think I might like the first season the most, however, as it honestly features the best acting imo. As the show gets more "Star Trek" the acting quality has just gone downhill. Still very excited for season four though.

Picard, however, angers me. It started with such great potential but ended up being a convoluted mish-mash of partially developed ideas. It had some great moments (the scene with all of the Rios holos comes to mind), but some utterly awful ones (the Icheb scene, the one where Picard just lets Seven kill Bjayzl, the death of Hugh, and the... the.. the COPY PASTE FLEET!!!). Still, I generally loved the characters (better in characterization one season than Disco's have been in 3), and have hope for a good season 2.

Finally, Short Treks intrigues me. Its first season was really good to me, all four episodes standing well on their own, even if a few just seemed to serve as tie-ins to the second season. The second season was also pretty good, the unique episodes like the tribble one and the animated tos one standing out as something special, the clear Pike and Picard tie-ins being just that, and the weird children's one being enjoyably weird enough that I'd probably watch it again. What really excites me is the series' future, however. Kurtzman has suggested that he wishes to see more and more unique short treks in the vein of the truly standalone eps from Seasons 1 and 2, things that flesh out the trek universe and serve no purpose other than doing that. As it stands right now, the show is fine, but a Trek anthology series has infinite potential.
