Just had a quick look through the Anchor bay BLu-ray of the origional MOTHERS DAY.
Unfortunately for some region locked, the film looks STUNNING on blu-ray. I know thats probably an over-used term but it really does look great. If you can play multi-region blu's this one is highly reccomended. Great introduction from Cahrles Kaufman showing much of the ready Kaufman wit his brother Lloyd exhibits on the Troma discs!
