Another thing I really like, that is a lot more controversial:
I am really enjoying what they're doing with the Gorn...so far.
The whole "Starfleet thinks they're monsters thing!" kind of ignores that Starfleet has not always had a universally kind view of races that are violent towards them (Romulans, Klingons, etc). Add in the body-horror element, and it's easy to see why the visceral knee-jerk reaction, especially of people who were tormented by them, is hatred.
But bit by bit, the Gorn are being shown as more like what we saw in Arena than the monsters that La'an sees them as. Sure, it's an ongoing story and could still go tits-up as soon as the premiere of Season 3, but so far I think they're setting us up for something really unique in Star Trek.
And I'll admit, I have a private desire to see a Gorn V. Hirogen episode at some point in the future (Whoever wins, we lose, lol)
