It looks very little like any previous Halo game. They've tried to replicate the low res, low poly-count look of Halo:CE in modern high fidelity, but it looks totally like ass.
Halo: CE had a charm, but only because its graphics and therefore artistic design was forged within technical limits. Infinite trying to replicate that look in a modern eninge is a mistake. It's why everything looks so awkward.
It's why Craig became such a freaking meme in the first place.
If you think Infinite looks like Halo 2, 3, Reach, 4 or 5, you need to get your eyes checked.
