Its just another opinion, if i found 3 diffrent reviews that all said that the anime sucked, then yeah i would probably stay away from it, but otherwise i just try watching it for myself.
DO IT! I’d definitely read your reviews if all for the sake of disapproving them.
All a review is worth is for the reader to (re)view the material, that s/he's already seen/read, in a different perspective. I usually only read reviews of those animes that I had a bit of trouble comprehending in some way, which, in other words, I rarely do.
Honestly no I don't pay any attention to reviews of anime, at least not unless it's done by someone I know. If I'm going to trust someone to decide if an anime is worth watching or not I'll more than likely only really care to listen to what a friend has to say or someone who generally has the same taste in anime as I do. Otherwise most of the time the reviews aren't exactly helping since I don't enjoy the same things the reviewers do and I know 9/10 times the reviews are biased as hell.
