It's a pleasure to watch this kind of mystery film, a kind of clue on amphetamines. Is it the best of the genre? Certainly not: so many mythical series from the 80's to 2000 have explored the vein. But it is not the worst, thanks to the charming and efficient cast. Of course, this is a forerunner of sequels and we will certainly have the same pleasure to watch them, with carelessness and without impatience about the outcome. We may regret a little the choice of the actor or actress (let's keep the mystery) who will be the main suspect and whose charisma is quite close to the one of the dead character.
