NBC's Alien Encounter shows

Caught the first few shows I've been interested in watching, both of a science fiction nature. NBC's THRESHOLD features an alien invasion of John Carpenter's THE THING type, where alien contact spreads through a group changing them physically. The group of scientists out to track them down include Brett Spiner, so that makes it a must see. On the other hand, I was not impressed by the first episode of NBC's other SF show, SURFACE with a government conspiracy to cover up the existence of an unknown species of ocean dwelling creatures. I think the show is trying to spread its net too wide (if you'll forgive the metaphor) with the 'good' scientists, the brother out for revenge and two kids trying to hide one of the creatures ET style. With so many story lines and characters you don't care much for any of them. Personally, I'd end the kid plot really quick.

I'm curious about ABC's upcoming INVASION, which also features an alien race coming to Earth for who knows what.
