I used to like Johns, but he lost me somewhere around Blackest Night. That's when the repetition of his storytelling methods became very obvious to me.
The last really good story he wrote, imo, was Sinestro Wars.
While Doomsday Clock is solid, it still has a lot of trademark Johns-isms, one being a very decompressed storyline that keeps readers going because he keeps most of what's important a mystery for most of the story, and then before you know it, there's only a few issues left and he doesn't execute the finale of the story because it winds up being rushed, and he then starts to focus on setting up the next story, and thus the cycle continues, and we are left wondering, if you had so little time left for your conclusion, why spend a whole issue on the new Rorschach's origin?
Also, he tends to write the heroes in a bland way, but does a really good job with the villains and is very strong in world building. But at the heart of it, the hero often comes across as blah to me. This was true with his GL run, Aquaman, Superman, JL, etc.
I remember reading Blackest Night, and after reading the 4th or 5th issue, I was thinking to myself, why do Hal and Barry feel off to me? That same night, I read the GL/Flash Brave and the Bold trade I had just bought (by Mark Waid), and the contrast was pretty stark. Waid had a clear voice for each character. They popped. I got a sense of who they were. They weren't just characters who's purpose was to serve a larger story, but characters who's stories evolved out of who they were.
