And for people my age, THAT is the problem.
Stewart is at best Timothy Dalton-lite, and at worst ... well, look at second season, pretty much any show except Q WHO, because DeLancie brings out the best in him.
Or when he has to get emotional ... ogod, SAREK, GENERATIONS, FC ... practically ShatLevel stuff.
I think Steven Macht (Steven King's GRAVEYARD SHIFT), who was in the running, would have been very good.
Well, I'm in between. I'm Wil Wheaton's age. To depart from the generational faux controversy, it is interesting and valid to see comparisons of Shat and Stewart, having both had Shakespearian backgrounds. I can understand the parodies and why some equate it to bad acting when someone like Stewart projects his lines from the Bridge like he's projecting to the back of a large theater.
But ultimately we're talking about style here, not substance. The substance of Stewart as Picard is top notch. Some people just have a preference for different styles, similar to episode content preferences, or choice of humor. Stewart has a lot of "classical" in him, some would prefer other styles.
So any opinion about casting, or miscasting, is valid enough, but its more constructive to frame it in a less combative way: Stewart is a fine actor, but I would prefer XYZ because...rather than to say "he sucks as Picard". There's no discussion in such statements.
