Why would you hate it just because because someone else does? You might see it in a new light, maybe respect the original more like Ameela, but hate the new game? He mostly complains about the story/writing, which in the PS4 game's case, let's admit it, is preeetty bad.
It's funny though, how most of the people anylizing what's bad about R&C PS4 seem to misunderstand it's creation process. They all act like the movie and the game was a one, big project, both produts developed simultaneously under direction of Insomniac Games, or even better, that the movie was based on the PS4 game (with all these "the movie just reuses game's cutscenes" complaints around the web)… But it is the movie that came first and according to Shaun McCabe it wasn't until 10 months before the movie's planned release date (Spring 2015) that they actually started to work on it! So little do people know, but what we got is actually another rushed Ratchet game that turned out way better than it should (when the movie got pulled back, the game was pretty much finished, so all they could do with extra time were minor tweaks and bug testing). I still think it is the least innovative, pretty flawed and perhaps the worst written (and I'm taking all the IG games and PSP spin-offs into account) game in the series, but for what they got to work with… This could've been much worse.
