"Le Martien de Noël" ("The Christmas Martian) is a very low budget and cheesy French-Canadian film. The version I saw was dubbed into English and the print was extremely overexposed.
I noticed that several reviewers gave this film a high score and loved it growing up. Well, perhaps you might love the film if you grew up watching it. As for me, I never saw it before today and thought it was a rather silly and cheesy film...sort of like a lower budget "Santa Claus Conquers the Martians" in quality. In other words, it's a pretty dopey movie...the sort most people either would never watch or they'd watch it an make fun of it.
The story is set in some small Canadian town. Two young kids happen upon a creepy Martian (he is essentially a guy in a raccoon coat with a net over his face) who has a strong penchant for eating candy. They play together in the snow quite a bit and help him repair his ship so he can head back home.
By most objective standards, this is a bad movie. The acting is amateurish, the costumes pretty cheap and the sound effects rather poor and a bit annoying. But if you enjoy this for nostalgic reasons, more power to you As for me, as an adult seeing it for the first time, it was pretty tough viewing.
