With all due respect, this post is ridiculous. While you are entitled to your opinion, many others do not share it.
1. Disney IS about imagination and innovation, and I think to dismiss Marvel, Pixar, Lucasfilms, or any of the companies Disney has bought as lacking either imagination or innovation is to simply not know the companies well or the products they've created. Marvel is writing modern myths. You might not find them all that interesting, but many folks do, and many of us find the stories to be quite imaginative and the long form multi-platform and movie style of telling a larger epic tale to be quite innovative.
2. I could make an argument about how Ironman 3 teaches about self-confidence and dealing with traumatic events. I could make an argument about how Ironman 3 teaches to treat others with respect for you never know how your actions will have ramifications. Instead, I'll simply point out that there is no universal standard of family values and that each family may find value in something differently. I found Iron Man 3 to be primarily a movie for adults, but one that I could watch with my children when they are older and have a meaningful discussion about the topics I mentioned earlier.
3. Your final point is part of a larger aspect of Disney Fans that really bothers me. I respect your desire for a less intense immersive experience, but why do you feel that your preference should mean the lack of options for others? How would a Marvel land, which you could simply choose not to visit, impact your negatively at all? Disney has to cater to a wide audience and I think the Marvel properties could help diversify that audience and appeal. Another example is the Disney Jr. stuff in the parks. Up until two years ago I thought it was a waste of space, I didn't hate it or want to see it go away, but I did wish it were filled with something I would want to experience. Since then I've had two children who both LOVE the Disney Jr. shows. This has really opened up my eyes to how Disney does an excellent job of providing options for everyone.
4. The idea that because you are tired of something everyone else should stop talking about it. Instead, why not simply leave the thread? I suspect it's because you don't like the fact that others are excited about this because as demand grows for Marvel products and experiences, Disney's desire to deal with Universal will also grow. Your best best is simply to ignore these posts and go join a conversation that is to your liking.
5. Finally, telling someone to grow up because they like Marvel Comics is rude and very much a bullying way of trying to win an argument. A vast majority of the people who visit Disney do so to experience some of the magic of childhood in a safe place that allows us to see the world with a sense of wonder. For some folks that means riding Peter Pan or Small World, for others it's Space Mountain or Big Thunder. But not everyone grew up in the 70's or 80's and now we have a new generation who feel nostalgia for Hollywood Studios, Animal Kingdom, and the Pixar Properties. For many men reading comic books was a part of childhood, and Marvel Comics are some of the most beloved by these folks. For me, sharing the stories of Captain America or Thor with a child provides the same connection to my childhood as watching the Little Mermaid might for someone else. I don't deny that there are stylistic differences between Marvel and what most would consider the classic Disney, but Disney itself has done some daring things that weren't all talking mice and spoonfuls of sugar. Lest we forget that Pirates is about the sack and rape of a coastal town. The Haunted Mansion is a journey through the world of the occult. Expedition Everest is about encountering a monster that would likely kill you.
I really do respect your opinion in regards to disliking Marvel, I feel the same way about DC Comics
. But, I have a serious problem with the attitude of being dismissive and ridiculing others likes/hobbies. I hope you can see that even though you wouldn't enjoy this type of stuff in the park many children and adults would, and that Disney has a history of trying to cater to all of their guests in an inclusive way, not an exclusive one.
