Feeling lonely and slightly unappreciated he leaves the safety of the bunker and heads out on a perilous journey across the surface to reunite with her.
This light and fluffy postapocalyptic tale mixes the tone of Zombieland with the Fallout computer game setting (minus the nukes) adds a few homages to Tremors and plays for cartoonish fun.
Which it succeeds rather well at.
In a world of movies dominated by things wanting to be the new YA franchise hit, comic or other on point IP adaptations or stuffed with expensive talent and promotion it's a genuinely straightforward low budget family adventure where all the budget is on screen.
OK we get a Michael Rooker cameo but I bet he's cheap even now post GotG and he's good value all the time he's on screen. Everybody does their job well, lead Dylan O'Brien is great and there's a dog and a sassy but cute kid. The monster effects are sparsely used and excellent and the obvious sequel signalling is inoffensive. I'd watch another one. If the pandemic hadn't messed with its release I think it might have been a mild hit.
Recommended for some light fun, 7/10.
