Looks like Anderson is on prednisone...my grandfather had that same look...it's fluid retention caused by the steroid...if that's indeed what's going on with him...
The going back/forth was a little annoying, but BSG did it a lot in many episodes and it wasn't too bad...just a quick way of establishing someone's back-story. SGA did it a few times also, as I recall.
It was a little better than I was expecting and the previews look interesting, but I'm really hoping they don't turn it into a cross between Lost In Space (looks like it already) and Space 1999, where they find weird new planets and races every week.
Shanks' appearance amounted to a cameo... Tapping and Anderson did a tad bit better. Still, it was good seeing them (briefly) again.
I'll give the show some time to get some legs and see where it starts taking us, but does Dr. Rush remind anyone else of a pseudo-Baltar?
