I watched an old Blockbuster copy of “Gladiator” (2000) the other day. I know you can now watch it in Blu-Ray on a widescreen, HD TV, but the blood seemed to splatter plenty good enough for me in the VHS version on my 24-inch set. Despite wearing a skirt, Russell Crowe is at his manliest in this classic tale of betrayal, revenge, second chances and double-crosses. And blood. Lots of blood. It’s probably just as well, otherwise the violence would have gotten pretty cartoonish. I mean, you’ve got huge dudes in metal face masks swinging big, chain-with-the-spiked-ball-on-the-end thingys and all.
