I guess I'm one of the few people that really likes time travel stories. 
Bring 'em on!
Also, I second, third, and infinity the points already raised about technobabble. The important thing is character and motivation. If you stay true to both, and present a good story or situation that the viewer can get lost in, audiences generally WON'T CARE right off the bat if your plot device is technically accurate or feasible. Eventually, they probably will, but that's AFTER they've enjoyed the story and absorbed its dramatic impact. Of course, this being STAR TREK, eventually someone will quibble. It's the nature of the beast. But honestly, if you REALLY feel the need to detail us to death with pseudo-science or what-have-you, make that one of the last things you do to the script (i.e. research the details AFTER you've fully developed the human interaction and emotion). Just my opinion, mind ya.
And about actors being "in shape": pears are shapes.
Seriously, come on. I admit I notice it at beginnings of episodes, but if the story's involving enough and you care about the character, as you progress it becomes much less of an issue.
And as a former actor myself (mostly theater, some commercial but all locally Dallas, so no, you most likely have never seen me ), I can assure you that no matter how much YOU notice someone's gut or double chin while you're streaming a free video on the Net, the actor him or herself is WAY MORE AWARE OF IT than you are. Every time. And they're probably doing something about it if they're intending to reprise their roles. Technically, I suppose the military aspect of STAR TREK would lead to some level of fitness among the crew, but if you're worried about that, then you're setting truly unfair standards for a fan production. IOW, until food synthesizers are status quo, the fact remains that there is a Burger King on every corner.
