This is a simple concept that I would like Crunchyroll to add to the site.
(helpful) not helpful
Like, and dislike.
Unfortunately helpful and not helpful are prematurely based on if the I liked it, or I didn't like the review. sometimes' it's based on arbitrary rules,
"The review's too long, to short, they've seen 1 episode (circular logic)"
Valid reasons: The reviewer had too much bias, the review had nothing to do with the show.
The other solution is to make reviews more strict in the user agreement but that would really make a lot of people mad if say the review was too short, then extend the amount to about 2 paragraphs, or if the helpful not helpful becomes moderator only.
This is why I would like them to add like or not, or simply only helpful.
