I'm on a different computer now so I've seen it. That Aquaman stuff was cool (bermuda triangle, Atlantis), everything else looked pretty much like I was afraid it would. They need to make a cool Aquaman movie and not this Dawson's Creek crap.
I agree with Fettastic that the Aquaman stuff was the only cool part. It gives me hope that a Namor or Aquaman movie could kick serious ass, especially since the little bit of action we saw there looked fairly impressive, especially for a TV show.
