Dark Knight Rises and Man of Steel were not bad films. Nowhere NEAR as bad as X Men 3 and X Men Origins: Wolverine (I would put Fantastic 4 in here, but...heck, Fantastic 4 and Silver Surfer too). Rises was disappointing, but it wasn't going to be anything else after the masterpiece that was The Dark Knight. Man of Steel could have been better, yes, but as someone who doesn't like Superman (though I am being persuaded that he is a better hero than I give him credit for), I enjoyed it.
I get Bob's point, but Rises and Man of Steel didn't need to be name-dropped as they were well received by fans and critics (moreso than the others mentioned, anyway). However, I am not looking forward to Batman vs Superman. It's turning into Justice League, but it won't work as the characters they are putting on screen won't resonate with the audience very well. Worked for Marvel due to their commitment to the characters individually, but this looks like WB are putting Batman, Superman, and Wonder Woman to the forefront and saying 'Oh yeah, there are these other guys too'. They REALLY need to reconsider what they're doing with the separation of their TV heroes and their film heroes. I like Grant Gustin as Flash, but will I like Ezra Miller? Probably not, as it'll be a completely different Flash that will only have 2 hours to prove himself NEXT TO BATMAN, SUPERMAN, AND WONDER WOMAN.
Sorry, rant over. Whilst there's so many superhero films at the moment, only individual strands will end. Warner Bros, with their approach to Justice League, may well kill off interest in their films what with their rush to make Justice League.
