I didn't mind the silly technobabble we had to use to get them on the holodeck. I was just glad they got them there. I can forgive a lot of implausible premises if the end result is actually enjoyable. It was fun for both the viewers and the actors. I'm sure as actor, it's just great fun to take on these deliciously campy roles and just ham it up. Nana Visitor and Avery Brooks were particularly enjoyable.
And seriously, if you don't like an episode that includes Garak, there's something wrong with you.
