I agree, this is a real thorn in my side. I can't stand how all of a sudden anything old is "cheesy" and needs to be improved upon. Sure, TOS had it's share of dumb moments, but chalk those up to bad writing on those particular eps. If you can't enjoy something because the visual effects aren't up to today's "standards" then you have no imagination whatsoever. On a related note, I can't stand it when I ask someone how a movie was, and they say "The special effects were really good!"
Hey, that's great, but effects are icing on the cake.
