So the weak points of this car is having too much configurations that can be chosen, and being fast..... are they kidding?
Maybe the problem here is that BMW paid them less than competitors. I can't really figure out why the M5 is so heavy that they compare it to a bank vault, and the E63 AMG is good (4,389 lb vs 4048 lb).

The RS6 weight 4,431 lb so it's the whole segment that has grown in weight. In this context the M5 it's not a bad car, it's the reviewer that can't understand what "luxury sedan" means.
