The poster just is a throwback to the 80's grindhouse movies that the original was lumped into...like I Spit on your Grave and Basketcase.
I remember seeing Evil Dead2 and HATING IT! I wasnt ready apparently and did not appreciate the camp and Three Stooges bits with the UNDEAD. After loving Army of Darkness I got it...I think I was wanting a serious horror movie at the time...which is hilarious as I type this..serious horror movie.
Oh yeah, duh.
This remake apparently throws the camp out the window and goes full on demon terror.
