"Viu-hah hah-taja" is a Spede comedy about two spacemen who "stop on this planet", "have eight eyes and six legs" and who take the shapes of two Finns. The script is full of these clichés. There's even an absent-minded professor (played by the mildly amusing Pentti Siimes) who constantly tells people how he is such an absent-minded professor.
The music (this time not by Jaakko Salo) is highly annoying and the editing adds to the incoherence of the film.
Granted, there are a few slightly amusing puns in the first two minutes and the bad Finnish succeeds for a while too. But if you, as I, thought the anchorman-unintentionally-ridicules-himself gag in "Bruce Almighty" is dragged out a little too long, you haven't seen this.
Spede has a brief cameo and he's even referred to in a joke. Now, I have respect for the man; he did some very good stuff, too. But unfortunately, to me "Viu-hah hah-taja" is unfunny, incoherent, embarrassing and - worst of all - boring. You can nonetheless always give it go. To each his own, as you can see.
