I wouldn't say I'm "hurt" per se, you just have one studio that mostly knows what it's doing vs another one that mostly doesn't. In a perfect world we would have two successful acclaimed movie franchises going at it, alas that just isn't the case. The MCU has its fair share of problems, the positives just happen to outweigh the negatives, as the public clearly seems to agree, while with WB unfortunately it's the opposite. I had no regrets about the DCEU while I was watching the Infinity War trailer, because it's just a different situation. As you said, Marvel took their time and had a clear vision, while WB instead, decided to rush after them. They will hopefully learn from that mistake and have a better planning now. One can only hope.
By the way, am I the only one who's tired of waiting for the Soul Stone? Where the hell is that damn thing.
