I don't believe I can watch it again. And I don't know if the proper question is if it's a movie one can "like." The blood wasn't the problem; I've seen a great many films with more blood. For me, it's the agony that Christ went through that I can't see again.
I'm like you. I saw it once and was moved more than any other movie I've ever seen. However, I didn't go see it again and I bought the DVD months ago and haven't watched it yet.
