Oh, please don't feel like I'm defending the shitstorm that is nintendo voice chat. I'm just not a firm believer that 1 star reviews and 5 star reviews are ever truly accurate for an app or games actual performance.
Agreed, but that's the nature of consumer reviews. Products on Amazon, apps on an app store, or even things like customer service experience, anything lower than a 5/5 or 10/10 is flagged, and bad experiences for any reason usually get a 1/10 or 1/5, etc. It's just the nature of review systems with sliding scales. I remember I got some $8 USB wire from Amazon and gave it a 4/5 saying like "It's a functioning wire, good price, pretty solid, material seems kinda brittle, but over all pretty good." And I got an email from the company like 4 hours later which gave me another wire for free to make up for "gross manufacturing defects" or something... I was like "Well.... I think a 4/5 is pretty good but... Ok!"
It's hard to find a review metric
less nuanced than traditional videogame reviews, but app store reviews are one of them.
For what it's worth, it makes sense. Apps are usually free (or very low cost), and they're usually meant to do one thing really well, or a small handful of things really well. So the binary review of "Should I download this app or not?" works for that 1 vs 5 binary.
