I don't normally link to trailers, but this is interesting to compare the TV version to the OVA version:

Of course, the OVA had a much bigger budget and probably a longer production schedule than the upcoming TV series, in terms of production time per minute of footage released. So the question is: how can they make the TV series intriguing when they can't make it look better? Especially when the OVA was visually inventive on practically every level?

The solution: don't try to out-do the OVA. Tell a story, and concentrate on interesting camera angles, not amazing animation.

Looks like the TV staff is taking that approach. It doesn't blow me away visually the way the OVA did. But it looks interesting.
