Last night's second episode of ABC's new drama Life on Mars, the American version of the British hit, took a precipitous drop in the ratings. This is really bad news because Life on Mars may be the best new show of the season, unless you're in love with The Mentalist, which I am not, or maybe The Eleventh Hour or My Own Worst Enemy has tickled your fancy.

What's clear is that ABC is trying to build a solid Thursday with Grey's Anatomy, Ugly Betty and Life on Mars, but Ugly Betty is off to a rocky start, Grey's isn't the powerhouse it once was, and the pressure is on Mars to keep Grey's lead and improve on it.

The show got off to a good start in the premiere, but last night was off 25%. That's not good.

(S01E09) If you've invested in this show from the start -- as I have -- here was a really welcome episode to fill in the blanks. Finally, we were given a little back story about Mary, the place she's living, her obnoxious family, her frustrations with her life and even Marshall's unrequited (or so he thinks) leering for his partner. There was even some good character stuff for Bobby D -- whom Mary colorfully calls a "little prick" -- which was really nice.

I liked the case of a Chicago cop doing a "Serpico" -- going undercover to rat out police corruption -- and winding up killing a fellow officer in self-defense and being forced into Witness Protection was on target. And unlike the ridiculous Russian girl in the pilot who was asking WITSEC for new breasts, this was a realistic relocation. He resented being stuck in Albuquerque, and proving that he wasn't a stone, he was attracted to Mary. Of course, Mary did cross a line by sleeping with the guy, but that was all right, too, because it proved that she wasn't a stone, too. And since it was back story, it was pre-Raphael.
