I watched The Gaming Brit's video on how Ratchet and Clank lost its edge.
If you have some time to kill I recommend you give it a watch.
I've only played the first game, but looking at how the remake differs from the original does show that some of the charm was lost.
From a gameplay perspective, the remake looks fantastic, but the dialogue is very weak compared to what was there before.
Being a movie tie-in probably had something to do with that. It felt very kiddie to what I've seen from the other games.
Still, I'm interested in giving the remake a shot someday.
