Ultra-violence, Shameless Copying

Rating: 3/10 (28 August 2017)

Others have noted how the violence is gratuitous and excessive. The story could surely be told without this, as evidenced by so many better movies about World War II.
However, I haven't seen any discussion of why Gibson and co. shamelessly copied Kubrick's drill sergeant hazing scene from Full Metal Jacket. This is far beyond mere homage, to a lengthy repeat of the nicknames ("Joker"), war face/yell, love-for-your-rife, etc. I found this copying outrageous and boring.
On the score of tedium, that goes for most of the film. The love story is without passion, although I grant that Garfield is a talented actor. The only drama is in the final exchange between Doss and Smitty.
Does anyone really believe that a veteran or anyone could interrupt a court martial and address the presiding judge? I guess this has to fall under the heading of total suspension of disbelief.
Finally, Hacksaw Ridge as depicted in the film is pretty dramatic and resembles Banzai Cliff on Saipan. But the Maeda Escarpment in Okinawa was apparently where Doss's exploits occurred.
