As to Seaquest its hard to say but probably more of the same that we saw in Season one which is almost universally seen as a good show. What would be better is if they can avoid the massive cast turn over that was seen between the three seasons.
I think there were several things in the first season that could have been used to make the things in the second season seem relatively - grounded?
As an example - Telepathy or at least ESP sensitives had been introduced in the first season story about the Library of Alexandra. Instead of the sudden full blown telepathy of Doctor Smith, make her more like the sensitives in the first season -
If we can keep Beacham as Dr Westphalen, then make Smith a Mission Specialist who floats round in the background, like Dr Levine and Dr Crane in the first season.
Jettison Chief Crocker and Lieutenant Krieg and retain Shen as the new Chief of the Boat and if you want another female cast member, then slip a Henderson type role into the Morale Officer slot.
Of course, you've then got Brody, Piccolo and Dagwood missing but Shen would also for the "young, attractive" mould in place of Brody, but also allow some further diversity. I think there was probably enough room for SeaQuest to handle an LGBT character and I think making Piccolo and Lukas roommates did lots for Lukas as a character, so I wonder if we completely revise Piccolo as a gay mission specialist (EVA Activity Specialist, but not biologically enhanced) and still have him as Lukas' roommate.
As for Dagwood, I'm a little unsure how you could adapt the Dagger Arc and still fit in with the science as established in the first season.
