The game isn't about revenge. It's about guilt, loss, and finding a way to live with your pain. You can call it trite but you may as well be calling the entire human condition trite. It's not the issue you're addressing that makes a story good or bad it's the way in which you address it and TLOU2 absolutely nailed it.
As i said, loss is a reeeeaally common theme and you see it in loads of games, so very common its kinda of a joke in some writing circles, or treated as cheap plot devices by others. Its far from something that should be seen as special and unique in any from any medium.
And honestly its handled horribly here, too much shock value for the sake of shock value and characters wallowing in self pity, feels like something teenagers writing edgy novels and fanfics come up with. If the story wasn't making it obvious its trying to be "serious", this could've passed as an 80s action B movie.
The first game did a much much better job at it in the 15 minutes prologue (though rest of the game is boring).
