How bad is it? It's awful bottom-of-the-barrel sludge, among the worst films from Brazil (see previous post).
Should you see it? No. I doubt you'd be able to watch all of it.
The Turkish remakes of popular films like E.T. and Star Wars all have their Brazilian counterparts, but instead of borrowing elements and making their own science fiction films, these are meant to be comedic and are aimed at children. By American standards, this is awful, but I've seen Brazilians defend it as okay for children. There is a chase scene involving a Volkswagen Beetle (in "Star Wars!") and the four heroes, a comedy troupe whose name translates roughly to "The Tramps," seem to think rolling their eyes is the height of comedy. The film seems way too long and padded, with slow motion chases, interminable slapstick fights (with sound effects that sound like they're from Three Stooges shorts) and unfunny jokes. There are a few quite (unintentionally) funny lines, but they are spaced too far apart.
