This is indeed not bad and provides silly, relaxing amusement if you don't expect much from it. You certainly don't have to think and the effects are fun rather than heavy-handed. The filmmakers have a strange idea of how to sequence their scenes sometimes -- they lose some of their continuity here -- mainly I guess because they're overly in love with dramatic shifts of locale and costume. Suddenly we are trekking through heavy snow; or running rapids and then falling over a huge waterfall in rubber rafts; or wrestling with crocodiles; or out in a desert surrounded by scrub-covered mountains; we're diving under water -- or is it just a swimming pool? How we get from point A to point B, or even where we are, are apparently not our concern. Also how to know where the main characters get all their gear since at one point they chuck most of it in the river. The hardihood of the cast has to be admired. They look to be doing a lot of their own stunts. For somebody learning French looking to add to their compendium of slang especially banlieue-style terms of abuse this is not to be missed and has something new in every scene.
