^ This might not be the "cool, hip" opinion to have but I actually quite like the idea of colorizing content that was originally B&W. As with anything, there are better and worse examples of it.
It's not the original intent, I know. But I'm sure if the original producers had an affordable choice, they'd have shot in color. I'm sure someone will come along and say, "No they wouldn't!" but history proves that as color became affordable, it became the default choice.
I'm sure the makers in 1963 would have wanted color. But it wasn't available, so they used techniques to make the B&W version look better. That's why the Daleks, in color photos of the time, have weird blue and other colors -- to make the end result in B&W look more striking. Ditto for the TARDIS console being pale green, when recorded onto B&W videotape, it's hue offsets the walls.
And the B&W originals still exist for the ultra purist!
I've heard zero complaints on that. Most existing fans are either against colorization or are upset that there's re-editing (regardless of reasons, which most people do know) and new music applied.
Having said that, I have a hard time picturing these colorized, truncated classic DW stories becoming popular. I'm assuming the intent is to get people who'd never what a long, B&W story with slow pacing by today's standard to watch these new versions. And it's just hard to see that group becoming very interested in these options.
^bingo.
That's the claimed intent, though I doubt modern audiences "can't handle the pacing", "can't handle black and white", "can't handle all the quiet", or whatever the reasons are. Yet Doctor Who used to hold its own and let good scripts and acting render the need for constant music unneeded, and between action and build-up scenes there was exposition or breather time. But the show was originally made to be watched episode-by-episode, not as an omnibus as well. In that aspect, it's interesting to update them, even if excised material may or may not add to the story's nuances.
In the end, will modern audiences really care? Did they for "The Daleks in Colour"?
But, I guess we'll see! It's a worthy experiment.
It will be for sure.
But notice in that the experiment is lessened by the fact that "The Daleks" was precedent, done first. It was also truncated to 75 minutes. "The War Games" is set to be 90 minutes, but that includes 10 minutes of new footage. Fans from a recent convention are also claiming that actors in the original had recorded new dialogue - whether or not that's true, but "The Daleks" had lines changed as well.
This new footage also includes a direct representation of the regeneration because, in 1969, there was no direct regeneration. It was kept vague and not made/shown on screen with a new actor, because the show might not have been renewed due to season 6's problems with hemorrhaging ratings, going over budget too often, story content failing -- it all allowed the Doctor's loosely-told origins to finally be explained as a final bookend, should the show not have been renewed. Fun fact, a couple of weeks later, Star Trek took the timeslot after season 6 ended. But WHO was renewed, season 7 was made and with Earth (via exile) as a focal point to keep costs down. It started great, ratings went downhill
again (from 8 to 5 million), and was teetering
again - thankfully the show was ultimately kept on and was revamped again for season 8, that worked with ratings going back up and
not going back down to 5, and the rest is history.
