We weren't sure if we should continue. Does the show get better?

Since you guys don't know me, for help as to the sort of shows we've found interesting; we enjoyed Sherlock, Downton Abbey, Lost, Doc Martin, Star Trek Next Generation, Doctor Who, House, Life, Burn Notice)

Clearly I'm not expecting Granite Flats to compare favorably to Sherlock, but just so you'd know what our tastes are.

Any other series I should be aware of?
