Time Runner (1993) ripoff, Flight of the Navigator crossed with Last Action Hero. Little kid with smart mouth learns that there is no justice for nerds in school; but then he gets a magical adventure thru time with his dumber but buffer adult self (Ryan Reynolds) to meet his father (Mark Ruffalo), and the kid looks like neither. Mom (Jennifer Garner) is hot but vapid. Future wife (Zoe Saldana) is hot and deadly.
Occasionally busts out a bit of personal growth and philosophy of how we deal with loss and anger. Usually interrupted by scarface mook, villain, and a bunch of masked stormtroopers showing up, and wouldn't you guess, the stormtroopers die and disintegrate, while named characters die offscreen. There's some blood and a wound at the beginning, which is immediately forgotten and nobody uses guns with bullets again until the end, when there's no blood from such bullets, weirdly inconsistent tone going from Unforgiven to Roy Rogers. Mostly they fight with shitty lightsaber ripoffs.
The props and sets are CGI nonsense with glowing blue lights everywhere. The soundtrack's trying to repeat the success of Guardians of the Galaxy with '70s-80s rock, but doesn't really let the songs play loud & long enough. They say the future's bad, but don't show us anything of it except space jets and a few props. Very little attempt at worldbuilding, it's just a bunch of sets for fights to happen in.
Utterly inoffensive, dumb, overly cute kids/family show, and should really have just been PG instead of PG-13 for its main audience.
★★☆☆☆
