What i consider a bad ending is an opinion.
It was a decently scarey movie, with creepy parts, and the acting was alright. The movie was just obvious at points. I knew what was going to happen next and it didn't thrill me. And at the end, I thought to myself, "Thats it?", instead of going, "Holy crap! Good movie."
I agree with most of digip's ideas. Ringu is awesome, so is the original Grudge. My best friend from high school had to spend the night because she was afraid to walk home after watching the Ring (american version). The original Japanese "The Eye" is also a good one.
