Lets not exaggerate things here. Marvel is currently having a very good run THIS year in film, but LAST YEAR they only gave us trash. Iron Man 3 and Thor 2 were wack films that gets overlooked due to their so-called crossover storyline. To tell the TRUTH, the whole DISNEY/MARVEL cinematic franchise is comparable to the height of the NO LIMIT RECORDS era in which you get a gang of movies back to back to back, not GREAT in quality, but is like fast food, that would quench your thirst until the next fast food meal, and MAYBE you get that "great" film that pushes it forward. But DO NOT get it twisted that because they are churning out a gang of superhero films that it means to be equated to greatness.
It doesn't matter if the movies aren't great because they're still succeeding in spite of it. Thor 1 was the definition of a "by the numbers" summer movie but the Thor brand and the Thor character became stronger as a result of it. It got people interested. Meanwhile the Green Lantern movie was released the same year and was a huge bomb... so obviously Marvel did something right.
Right now the Marvel brand is so strong that they're allotted a few missteps here and there. Iron Man 2 was complete and utter shyt but the first one was so good that most people are willing to forgive and forget. In fact I'm quite sure most people
did forget after they saw how good Avengers was.
There is no bigger movie franchise right now than Marvel. You can speak all you want about the varying quality from movie to movie but you know as well as I know that each new entry in that franchise demands a certain level of attention. GOTG was a fukkin no name supergroup and now they have the entire geek world at notice. That's the kind of power Marvel has right now. And what's even scarier is that there's no telling how far or how long they could keep going. We might still be heavily anticipating Marvel movies well into the 2020's if they keep this up.
If I told you 10 years ago that we would one day witness an epic Marvel superhero saga spanning the course of close to 20 movies all unified under one cohesive continuity... featuring all types of teamups and crossover events... what would your reaction might have been? Don't you think one bad or mediocre movie every few years would still be worth it?
