7/10 seems about fair. I didn't mind Bats in the team too much - I thought it fit his character that he would want to be there to make sure nobody screwed up. And that one scene where he scared the wraiths made me laugh.
Maybe not the best DC animated movie ever, but still much better than most of their live-action crap.
I thought Constantine was good. I liked Zatanna and Etrigan as well. Deadman was about as annoying as I usually find him. I felt the film was maybe a bit too overstuffed for its run time though. I did laugh at
Spoiler:.
them having to fight... let's call it Demon Number 2... in the one scene
As others have said, I thought it was good, but nothing mind-blowing. I felt they could have benefited from a longer run time, to help with the pacing, as well as fleshing some things out a bit better. Still, it was much more enjoyable than what the live-action DCEU has given us so far. And, quite frankly, better than the animated stuff we get from Marvel. At least, IMO.
