Matt Kerr's review published on Letterboxd :
This review may contain spoilers.
I must admit, I'm a sucker for time travel storylines. I always become fascinated with timelines that loop and divert and the consequences that the characters meddling in time has on the story. Part of this, however, is always getting a minor bit of frustration when the final product doesn't add up. Looper delivers by being a highly entertaining, fast paced action flick, which makes up for some of the more... inconvenient potholes. (spoilers below). Either way, like many films of its kind, this film is best when viewed with some friends, and makes for interesting conversation into the aspects of time travel and its effects on determinism.
The secondary characters outside of Daniels really didn't do much. There were also a couple of head-scratching errors that weren't explained and kind of rendered the whole plot meaningless, but I won't spoil them here.
Not exactly a boring movie, but you'll forget about it 5 minutes after it's over.
Aside from that, performances are good but the story messed up with the Dr Who easy "timey wimey" fix, and a few months after seeing it you will struggle to remember what happened.
Waste of the fine cast's talent.
When this movie comes on the TV I'm excited for the first hour then [I have a poor memory] go "oh wait, this turns into a farm house fantasy movie with MAGIC CHILD...." and change the channel.
Competently directed, well-acted, inexplicably dichotomous plot. And the farm, the crops, shotgun, MAGIC CHILD, boring.
