Not really. X-Men and Spider-man are more responsible for Man of Steel than Superman was.
An argument could be made for that, but, the only real reason that occurred was the first Batman franchise getting run into the ground.
Superman: The Movie is the godfather rof all modern day super hero movies and I really don't think MoS would've been made after the flop that returns was if it hadn't been for it's success.
And it was really more Blade than X-men and Spider-man that got things hopping again.
