I made a mistake...I watched a TS download version that wasn't the greatest of quality, even for TS.
Thought the film was brilliant..Really enjoyed the different angles to tell the same story.
Possible minor plot hole?:
When Harry Styles and his mates are on that grounded fishing trawler about to send Froggy-Gibson out like a lamb to slaughter - Tommy says "he saved our lives".
How the fuck did he know Froggy opened the ship's bolted kitchen door where they were in the process of drowning after it was torpedoed if he was hiding the fact that he was French? Froggy-Gibson jumps from the ship and then we see Tommy and Harry Styles come out from the submerged kitchen down below. There were still others abandoning ship at the same time as them.
