For reference, why IMDb is usually cited for mainstream stuff is because those stuff usually get hundreds of thousand if not millions of people rating them. So the small amount of people rating anime stuff like this pretty much means nothing in the context of IMDb’s reputation .I really don't know much about how useful IMDb is for anime, I just know it's pretty popular in general for TV series and after learning this episode is the highest rated I was elated and shared this. Had no idea it had such less reviews which I agree, makes it less credible.
And by review bombing I mean even if one person did it it would bring down the score
At the end of the day it didn't really matter, but being sore about the dub title I wanted to share this coz this sounded cool
