Sam Raimi

He alternated excellent works, especially in the early part of his career (La Casa 1 & 2, L'armata delle Tenebre, Soldi Sporchi), some decent ones (Darkman and Spiderman 1 & 2), and others that were mediocre or worse (The Gift, Pronti a morire, Gioco D'amore, Spider man 3, Drag Me to Hell).
