So my honest assesment so far:
Style - Great
Graphics - Also great
Speed/fluidity - Very good -- although it seems chunky sometimes due to the tons of blockstun
Footsies - Mostly nowhere to be found in a lot of matchups
The game prioritizes shoving lots of mixups down people's throats -- even moreso than in Injustice. The run button allows you to turn what would normally not be oki-able hard knockdowns into guessing games from as much as 75% screen away in some cases. This is aided by the prevalence of fast, longer-ranged overhead starters (Kung's f2, D'Vorah's f2, Sub's B2, Quan's b2) that are very strong.
In addition, much of the cast has canned footsie strings that allow you to travel about half screen in 2-3 hits. Even if the first hit whiffed, the others might reach. The game is absolutely dominated by them, and combined with the run button they're the reason we're seeing less footsie/spacing based gameplay than Injustice or MK9.
Another side result of these strings, along with the combo system, is that there's a LOT of corner carry in this game. There are several top characters who will automatically corner you nearly every time they open you up. Any Raiden combo ending in superman, most of Lao's BnB's, Jax's combos, and a good deal of Kung Jin's stuff, Sub Zero etc. This means that you end up spending a lot more time in the corner, blocking your way out of mixups.
There's a lot less spacing and a lot more staying in people's faces due to the combination of those three factors (run button, long-distance strings, and corner carry). But this makes it a personal taste. Anyone who's a fan of nonstop rushdown, continuous mixups, and being in people's faces all the time will love this game.
I like the fact that unlike MK9, a lot of moves are negative, which means it's a lot harder to just throw move after move out on block. Having far fewer 0 on block or plus frame moves forces people to really consider which buttons they hit and removes a lot of braindead pressure. However for this to matter most, you want all characters to play by those rules. As balance patches are released, the fixes will no doubt help this part of the gameplay shine.
