I rated the first episode of this stellar TV series as 9/10, then watched the first half of the season to accord 8/10. Well, the final five episodes of “Maniac” ratchet up the weirdness and atmosphere even more. Jonah Hill in particular amps up the theatrics as he plays characters inside Owen Milgrim’s head and Emma Stone, as Annie Landsberg, remains flawless. The pharmaceutical trial spirals out of control as strange and wonderful fantasies seem to draw Owen and Annie together even inside their heads, while Dr. Fujita, Dr. Mantleray, and the latter’s mother play out another drama altogether. Sumptuously filmed and precisely choreographed, the series finishes on a high. Oh, and I roared with laughter during one scene with Owen as a high-pitched Icelandic spy.
