It was entertaining. But like any versus movie it frustrated me, and it not being as endlessly dark as BvS isn't enough to make this movie based on far inferior source material a superior movie.
Here's what I find funny though. Age of Ultron had a lot of material dedicated to assuring us there were NO Civilian Casualties, all for the purpose of sticking it to Man of Steel and appealing to that film's haters, and I criticized that aspect of it at the time. And now they did this storyline which is entirely dependent on there being civilian casualties. So it's like they are reveling they lied to us before.
