What looks promising or good?
Trailers tell us nothing. Anything can be made to look good in a trailer.
Is this going to be the same crew of producers and writers? How much new blood will be involved, who are they, and how much influence might they have? I've only heard about one guy, and he's just a "consultant" or something.
The only hope for this series is some new people with new ideas and the guts to really pursue them. Ideally, there needs to be a new person in charge who can take over and make the radical changes that are needed. Like Bryan Fuller with
Heroes.
