Ehhhh, yeah ... that isn't enough for me considering the huge role this plot device has. They're rare, but there's a whole box of them just sitting there as soon as the characters need them and the main character googles them and finds information and people debating about them easily within 10 seconds. Doesn't seem believably "rare". We get three wish pops in the movie and they ALWAYS worked without question and even the store clerk behaves like it's just normal ("he already got his wish"). Like WTF. Again, something like this would've instantantly become known in today's world, streamers/youtubers would literally make make videos on them to investigate, call numbers etc.
It just doesn't work for me. The movie is at its best when that stuff is in the background and yet, the whole movie relies on it, so it is impossible to ignore. It would've been better if the main character would've found some random shit in a dumpster or something, made the wish as a hail mary/joke and it was never spoken of again. Definitely not support hotlines/internet searches or some other unnecessary elements drawing attention to such a thing. Something like Death Note does the whole mysterious object thing a lot better, they should've copied that, minus the Shinigami. My 2 cents.
