There can never be enough Tomolak. So yes, this episode could have benefited from Tomolak. But you could pretty much say that for every episode.
I agree about Sela being kinda cheesy and lame. Maybe it would have been cooler if they found the alternate universe Tasha as an old prisoner of war or something (in old makeup)... It would be interesting to see if she was angry at picard for sending her back afterall, even though it was a different picard. That would have been better than Sela I think.... but I dunno. I love having Crosby back on the show though so I can forgive Sela's cheesiness.
"I HATE Vulcans!!!!" that was like a scooby doo ending or something.
That said, i love this both parts of this two parter. The first part is A+ trek all around, and Spock saves the second part.
The Part where they mess up riker's hair in the hologram at the end always makes me laugh. It looks so flat! I'm glad riker mentioned it.
