I can't speak for anybody else but for me, Burnham absolutely did a fantastic job with the second half of Inc. His fights are brutal, everything's fluid, and his style meshes with Morrison's writing on this run perfectly.
The resolution reinforces the idea that Batman will always be Batman because that hole that was created by his parents dying and his oath to justice will never be filled. It's there and it's dark but it's always going to be there just like he's always going to be around in Gotham. Loose ends were tied up and the last issue calls back to the first ever Batman issue which starts with Gordon speaking to Bruce Wayne.
There's a fuckton of great symbolism and just ingenious ideas/writing strewn about all of Morrison's run that we can talk about for fucking years but at the end of the day, it was 7 years of damn good Batman books filtered through a personal story of what happens when parents fight/go through a divorce.
As for the Morrison can do no wrong--that's shit's just silly, man. Don't trivialize people who hold one of the best Batman runs as just that, one of the best damn Batman runs.
With that said, people SHOULD read more Batman books aside Morrison's run, because there's just a wealth of great Bat-stories out there.
EDIT: For fuck's sake, Morrison brought Bat-mite into his run and it wasn't goofy, it was brilliant.
