I don't give out extremely low scores often. Mainly because if I hate it...I drop it. And obviously those, I don't rate. But also, assuming I still finished it, it has to be wrong on all aspects. Not just a personal reason. Honestly, even some of the ones I dropped I wouldn't rate that low. Just not my cup of tea.
