While I agree, 50s Primetime can be a blast with a good cast member, the reverse is true as well. I have been there at least 10 time in my lifetime, and 1/2 the time the CMs were boring, and just served the food, barely spoke to us. Made me nuts, as we could see and hear other wait staff going crazy and having fun at nearby tables. In desperation, my kids even tried feeding these servers lines, like asking where the bathroom was, etc. I realize they cannot do the exact same thing all the time, I get it, I mean that these severs on more than one occassion, did NOTHING special.
My family loves Sci Fi, it is our FIRST priority when making our PS arrangements. (they are past the character meal stage). We love the movie clips, and how the servers shout out some of the lines, etc
Both are winners, don't get me wrong. But we gave up on Primetime a few years ago.
