Remember the old saying from T2 that Sara Conner passed on to John? This is a feature film all about it. Even if events are altered, is the overall course of history pre-determined? The premise probably looked great in a script, but Mennan Yapo couldn't get over the atmosphere hurdle. For a drama like this, you need some distinct atmoshpere -- for example, some hints that the alternate realities are being explored. Premonition wasn't a complete disaster, it just lacked the artistic umph to make it really likeable.
Rent it only if other flicks are out of stock at the woefully stocked Blockbuster.
