these original episodes have been meticulously colourised and enhanced with updated visual effects edited into a new, 90-minute feature-length experience
Are you kidding me? Yes, at 10×25 minutes War games is long, even for the period, but it is also a well paced and cohesive story as it is.
You can probably shave 5 mins of each episode to lose the title sequence, credits, and overlapping cliffhangers — but that still leaves more than twice the 1½ hour playing time they edited it down to.
I understand the BBC could only reasonably colourise so many minutes, but why then pick a story that arguably in its most basic form is longer than they can pull off?
