Like most Ryan Murphy vehicles, 'The Prom' soon overstays its welcome. It overdoses on sparkle and star power to overcome the inconsistencies in its story and characters. The film's biggest crime may be stuffing itself with too many subplots, some of which are just time consuming, and, at the end of the day, aren't needed. But despite its shortcomings, 'The Prom' has its winning moments with the cast is having a blast throughout, and it's utterly infectious.
