I think the problem is two episodes wasn't enough for the Paxton/Samuels arc. There could have been more hints and references to the buildup sprinkled through the season. It just seemed rushed, but it would have made for a better final episode than that excuse for a valentine.
Well Paxton's rolemodel... what's his face that Colonel... was in a TOS episode. But I agree, if they had introduced Terra Prime starting with Home with brief snippets and mentions maybe a cameo or two, then climaxed with that, it would've been great.
