Games, Movies, TV series that need a second chance/reboot?

I am starting this thread because I can't believe we still aren't seeing a series of Dune films, Dune RPGS, Point & Clicks and turn based strategy games.

Its one of the biggest, most intricate space opera's of all time, it blows most if not all other space series out the water. The original Strategy games were a huge hit! The original film was bad, but it was back in the days of doing one film then maybe sequels instead of a Harry Potter/Lord of the Rings/Avengers style of just splitting it into a trilogy. I really liked the mini series with James McAvoy, it was pretty fantastic but it only covered the first 60-70 years and the beginning of the worm kings reign.

Basically, why aren't people all over Dune? My other thought leads towards The Watchmen, the film was perhaps too ambitious for one film, lots was missed out from the graphic novel, not to mention completely changing the ending, SQUID indeed. Series of films or a TV series would better suit it in my opinion, include the comic in the comic as well this time because its integral to the real ending. Don't fob us off with Gerard Butler doing a special DVD copy of the comic aside from the film.

What other huge media hasn't been touched in 20 years(or longer!)or maybe never that really deserves it? Genuinely interested in new ideas I haven't thought of, make me angry about the injustice! Don't suggest things that are constantly re-booted like Spiderman, Superman, Batman. You can suggest things like Star Trek(overdue a new series?).

EDIT 2: It doesn't have to be a movie that needs a reboot or a Game that needs a sequel etc, basically what has untapped potential, for example I can't believe we never got like an open world Buffy choice based RPG.

Edit: Personal list of things needing new media(constantly updated).

1. Dune (how does this have no new media at all, at this point I'd take a youtube series)
2. Watchmen (same as above)
3. Farscape (id like to see a new series/game, but the cast is old)
4. Star Trek (New Original TV series, not reboot old via film) - Apparently happening!
5. Buffy the Vampire Slayer (New Buffy, reboot the entire show from the start)
6. Jayce and the Wheeled Warriors (DID HE FIND HIS MAGIC ROOT?!)
7. Quantum Leap (Let Sam get home :'(, new series, same cast of people who are alive)
8. FlashForward (victim of the writers strike, looked packed with potential)
