So what? I regularly take a massive detour via Oxford Circus on a tube
journey from Warwick Avenue to Victoria. If you were doing that journey
above ground it would be an insane route to take. If you're doing the
journey by tube it would be insane to go any other way.
Ah, but that's why I think that they should route it instead via Green
Park-Charing Cross-Temple/Aldwych-Holborn; then it would be a fairly
direct route to Green Park, and 1 stop on the victoria line.

I did wonder what the Underground map will look like post-Crossrail -
assuming it gets incorporated. The eastern side of zone 1 is going to look
very different.
Messy. Crossrail parallels the central line, but doesn't stop at the
same stations, although they do share some (like Tottenham Court
Road), so it has to keep dipping down to the central line, and
returning to a parallel route.
