Enjoyed the episode despite it being lifted from Alien, Aliens and Predator in so many ways that it's almost in copyright infringement territory... Hemmer's leaving was unfortunate as I enjoyed his character (especially in the fantasy episode), but it was done with a degree of class rather than just *poof* he's dead. La'an's leaving was just a write-out and done too quickly. "I gotta go find whatever, so here's my resignation, don't fight me on it" and exit stage left. I agree, plenty of "strong female" roles still in the show, but her accent was something I enjoyed. And she can return at some point in the future, if they want to work it that way. I am hoping they don't bring Scotty in this soon, but I suppose they have to establish the character at some point and they've now eliminated Hemmer, so that's likely the next new character we'll see.
My main complaint (gripe?) with this episode is that here we are, in a prequel to TOS, probably 8 years or so prior to James Kirk being the captain of the Enterprise (with two main TOS characters already established in this series) and they know more about the Gorn now than they do in the TOS episode "Arena". And this from two encounters with the Gorn in the first season of SNW!
Granted, they're a formidable enemy, and it makes for entertaining television, but when Pike, Spock, Uhura and M'Benga already know more about them now, then what, did they forget everything (anything?) they learned prior to "Arena"? That's my biggest problem with sequel series'. The writers want to entertain and yet they forget (or just don't care) that if they establish too much more about something (like the Gorn) that seems to have been forgotten in the original series, it just doesn't work or make sense...
