After a couple more hours learning and upgrading the flight, this is quite fun, you slowly get back all your IV powers too basically and you're just wasting shit left and right. Only problem, no serious aerial combat yet. But when you get flying real fast inbetween everything (they added a bunch of walkways and stuff inbetween buildings so you can barnstorm), dodging missiles, grabbing souls, etc. it's great.
You can power up all the powers really really fast if you put off upgrading the weapons/etc. because you can trade the "cash" for the souls required. The high priced ultimate upgrade to the weapons are pretty cool for the most part. One is a throwback to Painkiller, sending the flying wooden stakes into dudes.
It's a really short game if you plow through, and they make a joke about how the loyalty missions and diversions and conquering territory are super vital to angering Satan and making him hate you and not in anyway an attempt to lengthen the game.
Also, Kinzie is just there for the co-op I realized, it's Gat's story. The chatter is slightly different but I figured I should stick to Gat for the "real" character stuff.
Saints Row, in hell, with flight and powers! $5 was an insane price since it's better than all the DLC for the last two games.
