Are Hollowtech II bottom bracket normal?
Assuming you have the BB installed properly (no cross threading) it is normal to have a little bit of resistance when they are new.  But honestly they don't feel as "free" as a square taper BB because of the resistance from the bearing seals.

Also, be sure to check the drive side cup of the BB every 3-6 months.  If you ride in wet conditions aim more for the 3 month side.  That cup has a tendency to seize up.  It happens with all steel ball outboard/hollowtech BB's and the only answer is a ceramic bearing model or a Chris King BB.
