i give a show a 3 if i really enjoy it for the first year or two and but then find it grow stale and stop plan to watch it and and eventually turn it off when i accidentally run across it . it especially annoy to be disappoint by a show you use to consider a favorite . ( when i give a low score for this reason i always comment so that it clear i be not slam the entire run of the show but only the late season . ) good performer but the material degrade across time . hope to see them turn back up on the schedule and preferably not in a spin off but in fresh scenario that allow them to develop and show off aspect of their talent we have not yet see .
