Some movies are off-beat, but enjoyable, but many movies are just mind-numbingly weird. "Motorama" fits not-so-nicely in the latter category. Many seem to like it because of endless guest appearances and a total lack of sense, but those two things can only take a movie so far, and "Motorama" simply doesn't have any other merits to its credit.
"Motorama" delights itself on plot improbabilities. Its main character, Gus, is a cussing 10-year old on a roadtrip across an imaginary country trying to collect game pieces to win $500 million. When interacting with adult figures, none of them seem to notice or be concerned with the fact that he's 10 years old. At first it's incredibly funny, but it quickly becomes just too unbelievable, especially considering the people he runs into and the fact that he seems so unfazed by a lot of the disturbing (to someone that age) imagery going on around him. Gus has no depth, and, as an anti-hero who has no problem causing misery for others to get his game pieces, it's hard to feel sorry for him when he encounters trouble.
That trouble is provided by a slew of guest appearances, each mistreating Gus in more and more strange ways. Besides making the already worn-out plot even more unbelievable and less enjoyable, the characters share Gus' lack of depth and are equally unmemorable. The character's actions can get a little interesting, but the actors themselves don't add anything to them, thus negating the whole point of getting big names (they could've been played by anyone and the character would've been the same). These guest appearances seem to have been signed more for marquee value than anything else.
"Motorama" should be interesting - it's a unique idea, but there's too little semblance of sense in the script for it to work. Incidents that should have a lasting effect on the anti-hero and the viewer don't, as the movie quickly moves from incident to incident, in the hope that something will eventually make the audience feel sorry or understanding for Gus. That never happens, as by doing so nothing is allowed to connect, it just jerks back and forth as if on a conveyor belt, one incident after another. With a story so nonsensical it ceases to be enjoyable, and a main character who never evolves to care for himself or anyone else on a higher level, "Motorama" has little to offer except a brat sneaking around and trying to get rich. Why should we care about that?
