That does present a problem, as a lot of Clark's best traits are things you slowly unfold, like an onion, and movies only have so many minutes in them.
Though, to look at the bolded part....you might be onto something here.
Summer blockbusters are meant to be empty popcorn fun. They're not designed to encourage a lot of thought or analysis or tackle serious social issues, they're just meant to hit you in the face with entertainment for a couple hours.
I wonder how well Man of Steel and BvS would have done if they had been released in the winter? Winter films tend to be the more dramatic, serious ones that are enhanced by some post-viewing consideration (at least it seems so to me, but I dont study film so Im just going with my gut here).
Would DC be better served by making their films winter/early spring releases? Take advantage of the christmas shopping rush or the "taxes just came in!" spending spurge in the spring? Now, just looking at the surface, winter films rarely make as much money as the summer releases, with a few exceptions like Harry Potter, but there are externalities to take into account as well. The reviews for MoS were mixed, and BvS even more so. BvS especially made serious bank its first week, and then plummeted afterwards as critics began bombing it. But if the films were released in a different, non-summer season where people are expecting something a little more cerebral, odds are those films might have gotten more positive reviews, which would have encouraged more people to see them once the critics started dropping their opinions after the opening weekend. It might be possible that MoS and BvS would have made just as much money in the winter as they did in the summer, just over a slightly longer period of time, and with better reviews which would in turn positively impact blu-ray sales, merchandise, and ticket sales for the sequel/s. Not to mention it would mean DC wouldnt have to compete with Marvel's releases as directly as they do in the summer months, which is a fight DC wont win.
WB certainly know their stuff better than I do so I assume they've considered this, though I feel fairly confident that I know comics better, and I gotta wonder if they ever stopped and thought about these films as something other than "superhero" movies that by Hollywood law must be summer blockbusters.
