Understandable to have difference in opinions on games, but I'm not quite seeing what you're saying about this one with what you said.
Joey only seems "insufferable" in the route where you end up sleeping with his gf, which is kind of an understandable response to have. Other than that, he seems to be a slightly obnoxious friend at most, but certainly not insufferable. As for Chris, he's a minor character that you can avoid a lot by making the "right" choices, if you will. Which, in my opinion, are easily noticeable choices that hint and lead on to what'll happen; so you can shut it down fairly easily.
Vanessa does fall under that character trope though, which isn't for everyone, so I don't have much to say on that since that's 100% preference lol. I don't see Ann as being eager to hook up with Chris, but rather naive with relationships with guys. Chris being more of a player type would easily be able to corrupt that naivety, but also it can be avoided with the right choices like mentioned previously.
As for the player, I took it for something closer to a self-insertable character with the vague background on him that we know of so far. Then again, it's only 0.5v, so he could get fleshed out more as the game develops later on if the developers decide to go that route.
Then again, like I said at the beginning, it's all about personal preference in the end really. I just think some of those comments aren't entirely accurate about the characters. Cheers for being kind about it and recognizing it may not be for you instead of flaming the devs for their game
