I'm still not going to recommend Dollhouse until the shows are good with some degree of consistency. Still, I no longer hope for it's swift cancellation.
The Unusuals takes the time slot of the late unlamented Life On Mars and also takes much of its predecessor's goofy yet violent charm. Set at a police station, most of the characters are detectives with some sort of odd quirk, which range from being rich to being a murderer. Many familiar faces pop up, notably Amber Tamblyn (Joan of Arcadia). Life On Mars had some interesting and intense drama but was clearly not going anywhere and the basic premise petered out very fast. The Unusuals is still feeling its way around, but in the right way: Start off with characters and good writing and let the situations develop.
I'm not going to recommend a series after only three episodes, but I'm enjoying The Unusuals a lot more than Life On Mars, and might be worth watching a few shows just to get up to speed on the characters before longer story arcs come into play.
