First, I agree about Spiderman III being too Hollywood, and not enough plot.
Second, Venom is neither Dark, nor mysterious. The character is lame, and the fact that they jumped to him as quickly as they did, when Spider-man has one of the largest and coolest rogues galleries in comics is nothing short of a crime.
Third, that new Superman design you found is crap. It looks like a '90s Image character. Christopher Reeve proved that the original costume DOES WORK on the big screen. Plus, forget iconic for a second, and consider that Superman falls just short of Mickey Mouse as one of the most recognized characters WORLD WIDE. Why would you change the costume when it is so marketable and familiar? It gives you more wiggle room with your casting, as, even if they aren't the perfect fit, the costume MAKES them Superman. I didn't think Brandon Routh would work, until I saw him in costume, and even that was muted and the shorts were shrunk to make me think maybe the "S" stood for Stripper, but it was still closer than that ridiculous design.
You say Superman's costume HAS to be modernized. Really? If you HAVE to change the costume from Superman's than why bother making a Superman movie? Sure, the X-Men opted for leather over spandex. Who cares? That idea makes sense, and those characters have changed their costumes within the comics a zillion times anyway. Superman's look has been tweaked, the boots have changed, the S size has changed, but overall, it's a brilliant design that has withstood 75 years. Plus, unlike other characters, his comes with the built in explanation of being An Alien Design made of Alien materials, which helps justify it looking "strange" or "out of place".
Fourth, quit pointing to The Batman franchise. Sure, the movies are good, but they aren't BATMAN. Batman should be the smartest, cleverest, most cunning, detective out there. The Bat films depict an idiot, who couldn't find a clue without Morgan Freeman, Alfred, and Gordon to hand it him; who relies entirely on his tech. rather than his brain.
Fifth, Daredevil sucked and it had nothing to do with Michael Clarke Duncan.
