 You can read the reviews and the knock is the a loss of "feel of the road".  I really don't agree.  Car is incredibly quick and responsive and kinda likes to be pushed a bit.  Never have a sense of control issue, the car just does everything you tell it to do and does it extremely well.  Many have commented it is the most beautiful and comfortable car they have been in.  I agree.  Have had it a year and zero issues (same as my 2014).  Quality level, fit and finish is outstanding.  It is quieter than previous 5 Series and I like that.  Very smooth ride and mated to the road.  Big improvements.......audio controls are vastly improved and imputing an address into the Nav system is down right simple.  Display is great, and touch screen easy to use as is IDrive.  Got head up display as part of package and love it although you cannot see it if you wear Polarized Glasses.  Standard sound system is fine (don't bother with over priced up grade).  Self parking is wild.....it works well (but a bit spooky to let go of wheel and let it do it's thing).  Biggest complaint is that Blind spot monitoring is not a standard item on a vehicle of this caliber.  Come only with expensive upgrade package..........this is dumb.  Last negative, forget the Car Play option.  Gets confused if you have a number of Bluetooth items coming off your IPhone (Audible, Spotify, Pandora).  IPhone works better with it off......wasted $300.  Overall on a scale of 1-10, it is a 9.8!!!
