Review | Pretty Little Liars

Air Date: Monday 1/2

Us Rating: *** 1/2

Be warned: Anyone who dismisses this drama -- about four high school girls stalked by a mysterious mad-person -- as a silly teen diversion will miss out on another seamless rush of thrills from one of TV's most intriguing young casts. The cops now suspect Aria (Lucy Hale) and her pals of murdering Alison (Sasha Pieterse) and have stuck them in community service for evidence-tampering. They go on the offensive against an increasingly agitated "A," leading to a must-see showdown. (ABC Family, 8 p.m.)
