Yes it's been emaciated like all the great tracks but there is still a lot of Spa left at Spa.
Anyway, I don't agree. Whilst a degree of risk is a necessary component
of all motor racing the Burnenville/Masta section of the old circuit was
ridiculously dangerous for the drivers whilst adding little to the
spectator experience (no big TV screens in those days, just an
unreliable Tannoy). The 1970 race was 28 laps with a lap time of around
3:28 whereas the 2016 event was 44 laps at about 1:46 per lap.
The new track has retained almost all the best features of the old Spa:
a long, fast straight; fast sweeping corners; elevation changes; a
double-apex corner and a hairpin, to say nothing of a long racing tradition.
Where I *do* agree with you is that bloody chicane! I never liked the
old Bus-stop but at least it was possible to get through it without
destroying the driver's rhythm but the new one is an abortion similar to
the "new" chicane at Barcelona. Won't stop me enjoying what is still the
best circuit of the year though :-)
There is an interesting (at least to me) article about the old Spa
