Monk (2002 - 2005) --- Sweetest show. Hampered by an odd variety of phobias and obsessive-compulsive tendencies that surfaced after his wife's murder, brilliant San Francisco police detective Adrian Monk (Tony Shalhoub) quits the force and begins working as a consultant on the SFPD's toughest cases. Monk's ex-superior, Capt. Stottlemeyer (Ted Levine), grudgingly calls on him for help.
Two Sarah Michelle Gellars?! Yes. Ioan Gruffudd?! Yes. Cliffhangers in each episode?! Yes. What more can one ask for? (Well, there's so much more that this show has to offer, buuuut, there's not enough room to list it all) ;)
