In abysmal 'role reversal' chick-flick "Mack & Rita" Elizabeth Lail (meh) is an 'old before her time' 30 year old yearning for the honest relaxation of old age... then boom, via Simon Rex's 'regression' sunbed (the same vessel that worked much better in "Meet Cute" btw) she transforms into Diane Keaton (embarrasingly awful) and starts living her 'true' life with oldies like Loretta Devine & Wendie Malick, while dating (ridiculously) Dustin Milligan (dreadful) - all under the nose of bff Taylor Paige (the one bright spark in this dull turd). Quite who director / co-writer Katie Aselton was aiming this garbage at is unclear, but what is clear is she missed them. Absolutely pitiful. Flush.
