Adjust your expectations
This is not a Saints Row game.
Imagine taking all the generic open world bits that nobody likes anymore and that is this game; a generic open world with absolutely no hook.
The actual world is very nice looking, a stylized future city very reminiscent of Overwatch but it is extremely small,likely the smallest "open world" I've ever been in.
I liked the majority of the characters they all had a decent backstory and fun special abilities.
80% of this game is extremely repetitive missions that take your through the exact same dungeon. The other 20% is okay story missions.
A strange thing happened to me towards the end of the game, I started treating it like an arcade beat em up game, I just stopped trying to be careful/not dying and just plowed through everything with reckless abandon and I started having some fun with it.
The most interesting thing about this game is thinking about what may have happened during the development of this game; it seems obvious that there must have been some extreme changes in course and scope over the development of this game. It feels like they sat down and came up with a great premise spent 2 years trying to make something out of it and failed, then pulled out the Saints Row engine and slapped this thing together in a year and put it out because they had to, I'd love to see a behind the scenes documentary.
If you play this like an open world collectathon you are going to hate this game and yourself. A much better option would be to mainline the story and get out but even that is not really worth the time.
