Went into this optimistic but I came out disappointed.
Animations are crap, texturing is awful and even if we resign to the idea that it's intentionally low quality in order to keep up with the action on screen (it shouldn't need to be when games like Titanfall can be equally chaotic yes visually, several grades above this), various visual elements stand out as being super-low resolution.
Even the AA solution is poor, heck there's aliasing all over the character select menus even. It's a very ugly game.
As for how it plays? It's okay. I only played a few rounds, and two co-op matches, but I found it felt rather monotonous, the game appears quite orientated towards coordination and team work, with AoE abilities, stuns and such, but with the janky and over the top animations, the game just looks much more visually busy than it needs to.
Heck, as a very basic example when Oscar Mike reloads, his arm covers more than half of his screen. It's visually obstructive without reason and I don't feel that much attention has been placed on how this may negatively impact the games design. That's an issue at the most basic level, but speaking more generally powers gunfire, animations etc. all interact to make an experience that's not that comfortable to play visually, and this has a cascading affect on how enjoyable the game is to play.
In regards to the singleplayer / co-op play, I found this very mindless. High health makes it very forgiving, and I found myself playing passively after a very short span of time. Enemies are bullet sponges and do not adapt or enforce immediate consequnces to your mistakes, therefore you can get into a habbit of holding R2 mindlessly until the game begins warning you that your shields are gone, or your low on health, then take cover for a bit. Even if you die, you simply respawn, no big deal. I'm sure there are difficulties which make this more engaging, but that doesn't help the gameplay overall, it should be entertaining at a basic level, and it just isn't for me. I shouldn't be falling asleep playing the missions on normal difficulty. They were very reminiscent of strikes on Destiny. About the same in quality, though I appreciate that the dialogue was better in Battleborn.
Stacked upon other issues, such as the lack of offline singleplayer and co-operative options, I don't see myself enjoying this. I have my hopes on Overwatch instead.
