My problem with the game is that, even if I enjoyed it, it seems the same Ratchet game as always. It doesn't do anything new. It looks great but it's totally forgettable. It's a great forgettable game, if that has any sense.
It's 10x better than 2016 ratchet. Actually a very fun, great looking game.
But I gree with your statements. It is repetitive but that might be ok..
The worst thing is how safe it is to not offend anyone. Ratchet lost any edge he had.
