Star Trek: OId Versus New

I was having a discussion recently with a Star Trek fan. I'm a fan, too, if not a Trekkie (or Trekker).

The big question, I guess, is what do you prefer, the original series or The New Generation. (Some prefer other spinoffs, but this is the central query.) I go with the original.

The comparison I use is the original is adults acting like they're kids, while the latter show is kids acting like they're adults. In the first series, they deal with deep issues of life and death, duty, freedom and so on, but they do it with a lustiness and excitement that seems like they're having fun with all that swashbuckling. But TNG has characters and issues who seem much smaller to me, but who try to act seriously to convince themselves how important everything is.

Plus, Kirk and Spock were such significant characters, it took FIVE actors to take their place in TNG: Picard and Riker for Kirk, Data, Worf and Troi for Spock.
