“Shifter” (* out of four) was an abysmal potboiler psychodrama about a young woman (Nicole Fancher) who begins to experience various painful and gruesome side effects after she experiments with time travel and she gradually begins to realize that her plans have backfired. Molasses-moving story is recommended only for those who thought the “Back To The Future” trilogy was in any way overrated; a real bore, despite Fancher’s sincere performance. Film’s underlying theme is how time is precious so don’t waste any of yours on this clunker.
