But Warped9, some of those actors are also dead and gone.
Yes, the actors in the roles you remember will never come back. And that is sad. I have great fondness for William Shatner, Leonard Nimoy, DeForest Kelley, Nichelle Nichols, George Takei, Walter Koenig and James Doohan. I thought they played their roles perfectly. But their time has gone, through a combination of old age and death. Shatner is hardly in heroic form anymore. None of them are, really. Could you make a passable movie staring Star Trek - The Old Guys? Certainly, but frankly, right now the franchise needs more than just a passable movie. It needs a big hit and if what we are reading is true, ST XI might well be that.
I will invoke the great traditions of Europe and say, "The King Is Dead. Long Live The King." I can also invoke the great tradition of Captain Kirk and say, "Gallivanting around the cosmos is a job for the young." Both work.
Look on the bright side. At least we'll get to see Nimoy play Spock one more time this way. That's something I thought I'd never see again.
