oh, there are plenty of those, though i only remember a few.
1. Dagashi Kashi - i heard it had good comedy so i watched it, but it hardly made me laugh...
2. Divine Gate - i had to stop watching it because the story was all over the place, if there was even a story.
3. Terra Formers - i don't know why i even watched this. the idea sounded gross to me, but many people were talking about it so i had to give it a try, and i wish i didn't :/
and it wasn't because of the gore, i just thought the deaths were pointless...
plus, it was gross.
