I watched over 2 and 1/2 hours and couldn't take much more. I decided to take a break and finish putting away toilet paper and paper towels from Sam's club I had purchased earlier in the day. It didn't help. Finished the 3 hrs and realized I now have great material to punish unruly inmates should they escape, kick in my door and demand a thriller with an 8.4 rating on IMBD. "Oppenheimer" I would should shout with enthusiasm. Or perhaps this is the beginning of going green and saving our planet earth: what started in the 1970's as reduce, reuse, recycle can now be referred as the movie Oppenheimer. It will be a spark for generations to come to.
