I'd love to see a Captain Worf TV/DVD-movie. Depending upon how it would be, I wouldn't even mind a Worf series. That having been said, Captain Worf could be the new Captain Sulu. Though, if the pattern holds, Michael Dorn could have a huge social media following on Facebook or its equivalent in 2030.
If either one of those happens I'd be happy just because I get to see new Star Trek series on my tv. At least until I saw it Not holding my breath but I'd particularly like to see the Worf one as he's one of my personal favourites character wise.
I think its ok to have a starship commanded by Worf, but I don't think that show should be called "Captain Worf" it shouldn't be all about him, unless he is a fighter pilot. Also the show would need something else besides just having a Klingon as Captain, there needs to be some concept like Voyager had one and Deep Space Nine, it can't be just about who commands the ship.
