disagree. i respect everyone's rating and it is useful for me to see a rating regardless of whether a drama has shown 0 1 or 2 episodes. im sure your human brain can comprehend the intentions behind the rating, whether it is an expectation rating when 0 episodes are shown, or a rating based ooff 1 episode.
people can review whatever they want to too, if u dont like it, downvoote it.
in fact, anilist although clunky, u can see statistics that show how much an anime's rating changes over the course of its screening. i dont find it very useful personally but u can see for example very interesting things like
for this seasons made in abyss
it went from mid 70s to mid 80s all in one final episode 13.
a rating at 00 episode and 1 episode carries as much weight for someone who is looking for a drama to watch. unless u want an arbitary number which is also reasonable because mal does not allow ur rating to be counted unless u have watched a certain percentile of the show.
personally i dont rate shows unless i have watched a high number of episodes or i am done with the show itself
