James Gunn’s Superman Teaser Trailer: Too Much Too Soon?

I have mixed feelings about James Gunn’s rendition of Superman in this teaser trailer. Gunn is brilliant at introducing new comic characters and new worlds to the big screen. I just don’t think this Superman is from our Earth. Gunn’s Superman is from a totally unfamiliar world with new heroes like Guy Gardner-Green Lantern, Hawkgirl, Mr. Terrific, Metamorpho and Superman’s dog Krypto. I also get the sense from the opening scene of this trailer that Superman can’t do this hero thing by himself. He needs help. He needs a team. He needs a Justice League.

Let’s look at the trailer below and let me know if James Gunn is attempting to put together a team to help Superman with EARTH’S INFINITE CRISIS.
