Good first half. Less so after that...
I thought the back and forth between the two Adams was pretty funny. Even the physical comedy between them was great. The younger actor really nailed Ryan Reynold's Deadpool-lite patter.
I wish they had focused on that.
Once it got deep into the time travel mission stuff, the younger Adam faded into the background and it became a goofy but forgettable sci-fi/action flick.
What was up with the light swords and staffs? Seemed like they were stuffed in there for the sake of a joke or two by young Adam. Otherwise, they seem pretty pointless.
And, again with the distracting CGI! That picture perfect HDR cabin in the woods with the non-specific golden-hued lighting. Living in BC my wife and recognized the location filming for much of it, but they coudn't find a real outdoor cabin somewhere to fill in?
