Boss Fights Great or Lacking?

What’s your opinion on boss fights in this game? Personally I thought they were pretty good overall. Harley, freeze, and talia felt great but clayface was a ranges strafe slog.

Then I played the talia showdown and wow. That was one of the most satisfying boss fights I’ve played since Arkham origins. I was only lvl 40 so probably made it harder on myself then I needed to but it was really awesome getting her timing down and even after it was close.
