Cute ending, and given the cancellation, I guess they had to give us something suitable in short order. They could have done much worse. Or just copied the original. I'm glad they did something different. And, yes, I was singing along to "Mona Lisas and Mad Hatters." The last shot...trippy, and very, very right. A giant 70's loafer step for mankind. On Mars. Yesssss.
Can I say I'm very happy Sam didn't go splat this time?
