Ryan Reynolds' well established brand of sarcastic quips isn't nearly enough to salvage this film. In fact, the humor isn't even a saving grace, as it's way more miss than hit, often feeling stilted and obligatory. The paper-thin plot doesn't bring anything new to the time travel genre, boiling down the typical elements to the absolute bare minimum. All talk of mechanics and paradoxes are swept under the rug without any meaningful explanation, with the allegedly high stakes often expressed through nebulous expository dialogue (e.g. when Reynolds explains to his younger self that 2050 is just like in terminator but worse). Combine all that with noticeably cheap special effects, less than compelling acting from most everyone involved, and ineffective sentimental moments, and the end result is a disappointingly forgettable mess.
