Abraham's is perfect for Star Wars, it will be a big hit the summer it is released then everyone will forget about it.
Name a tag line from any of his Star Trek abominations other than Lens Flares...
The beauty of Star Trek was it's use of language and story. The whole usage of "Tale of Two Cities" was just a footnote in the reboot. Kirk was too young to feel old, he had no life experience. The images and blockbuster effects were better in the 2nd movie but people forget that kind of stuff as soon as the next special effects blockbuster is released.
JJ can make 3 entertaining Star Wars movies and keep that merch machine making Lucas money, will they be remembered 40 years later like the 1st 2 movies are? I doubt it, just based on his track record.
