Life on Mars has a solid story, however it doesn't really deliver in the end, though the serial killer story was intense at the begining. The small cases that took place and created the puzzle of the main story, the relationship between the members of the police team and the performances, were the highlights of the series. Especially the cases were really interesting and entertaining. The bromance and the dynamics of the team were so good that I'm wishing that there would be a second season, taking that epilogue in mind and the fact that they didn't really explained why he went back in time and how. But overall, it was enjoyable.
