After eight seasons, "Psych" is off the case. The lighthearted series may have never been a ratings blockbuster or a regular on the awards circuit, but it featured nice chemistry between stars James Roday and Dulé Hill. The one-hour finale will be followed by "Psych After Pshow," featuring the series' star and executive producer, Steve Franks. 8 p.m. USA
