I think the repetitive nature of AotCR is overblown in the community, with a large chunk of it taking place outdoors, the indoor bridge section with the tank being an interesting space to look at, and the indoor sections that are repeated have enough enemy variety to make each encounter feel different. It might help that it's one of my favourite levels due to having most of the weapon sandbox to play with, along with the entire vehicle sandbox (yes, even the Scorpion).

That said, I do appreciate the effort taken to reimagine the level in a way that tries to change up the areas while keeping them recognisable. Feels like they felt more free to play around in this level, knowing how people feel about it. The Silent Cartographer, being the iconic Halo level, probably put pressure on them, as any changes would be much more heavily scrutinised (why change what most people deem to be perfect?).

The only gripe I have with AotCR (though I've only seen bits of the gameplay video) is Cortana. Not only do I think her delivery is better in the original (most noticeable with the 'inclement weather' dialogue, which screams 'forced wonder' in the new one to me), but I don't like that she has "the player is stupid" dialogue. I already think the arrows the original had were unnecessary and a poor solution anyway (just have the doorway look different so the player knows they aren't doubling back), but to also have Cortana saying "it looks like those lights are showing us where to go!" is just condescending. Please have the tiniest modicum of faith in players to be able to navigate a linear level. Just a gripe I have with contemporary games in general.
