The new cg cylons look phony. The old ones were cool and clunky. Remember the cool gold one? Or the gunslinger one? Cool stuff.
Don't get me wrong, I loved the old Cylons, even had one of the action figures (along with a Viper model, etc.). But they did look like guys in plastic suits, although that fit with the campy old BSG. The new Cylons fit the darker new BSG.
What I miss are the sparkly-brained commander Cylons.
I sorta like the new Cylons - they are lot scarier than the old ones, though, apparently, no more effective. Really, though, they are too noisy for a good combat unit. Never will figure out how one snuck up on Helo in the parking garage...
