Primetime Preview: Series Finale of Life on Mars

Life on Mars comes to an end tonight. Will the series finale be worth a live viewing or a DVR recording?

Here's what the show will be up against...

• 8:00 p.m. Elliot questions her future on Scrubs (ABC); Cal is obsessed with suicides on Lie to Me (Fox).
• 8:30 p.m - Ted brings his daughter work on Better Off Ted (ABC).
• 9:00 p.m. - We flashback to Kate's life on Lost (ABC); someone is going home on American Idol (Fox).
• 10:00 p.m. - The series finale of Life on Mars (ABC).

Will Ben still be smiling, or even alive, after tonight's new episode of Lost?
