Goofs

In taking the heavy box to the car, Max's effort is awkward and choppy, but his shadow is mechanically even and smooth.

Visually, the living room of Molly and Max' new apartment is large enough to comfortably accommodate a high school wrestling practice.

At 8:08, pedestrian steps appear within a long garbage pick-up alley. Really? Cars and garbage trucks commonly turn into citizens?? No, steps only suddenly appear for the sake of the plot.

On moving day, Max carries a box roughly 32x26x16. He can barely manage it, yet it only contains four hand weights and two books, which break through the bottom. Not only is the box far oversized for its few contents, the two books are already on the sidewalk before Max exits the house with the box that loses them. Furthermore, his Herculean effort to carry it doesn't match the contents' weight (guesstimated at 70 lbs.). He also hasn't disassembled the weights for a compact fit into the moving van either, where space is top priority.

On moving day, Molly reminds Max of taking only what they need. She's against him taking free weights (pointing out that he never uses them) but is okay with him taking a box of children's toys he no longer plays with.

Max arrives last to school, where the bicycle rake is empty till Max adds his (suggesting he's the only student to come by bike). At the end of the school day, he uses his bike to get the better of school bullies, whereby they give chase on their bikes. Bikes? What bikes? Wherefrom came these bikes?

At 21:14, the giant Fire Elementor grabs Max around his calves and, swinging him like a club, forcefully strikes him head first upon the stone canyon floor. This is literally a killer move, and Max, bare-headed, should sustain injuries worse than a concussion; yet, he survives, hurt but intact and conscious, without so much as a some crazy explanation like the Steel Suit generating a kinetic energy displacement field of some kind.
