they already stated long ago that the game will share the same scene between each segment, you gonna have to play it again but only with different character. also, you already in chapter 3, which is half of the campaign which also means that the plot is in the climax. understand how the plot works, climax usually have a lot of actions sequence.
every game has its flaws correct?
so yes, some part gets repetitive. what makes you think other games don't get repetitive? even classic RE have tons of repetitive things (mostly collecting A and B to get to C) but that's not necessary a bad thing. QTE isn't really a problem, since the previous two has a lot of QTE as well. heck, there are other games that have so much worse QTE than this.
let the critics be, not all of them are RE fans. sometimes they just review it cuz they wanna bash it, some are just starting to play RE game.
don't give a **** about the criticism. you might think that the game is great but the critics say otherwise.
you play it, you finish the game, and you judge it yourself.
