Mm, I dunno. I was in until the German U-boat commander...called to mock him? And they somehow almost capsized the ship to deflect a torpedo, ostensibly at a U-boat? Eh...
Watched it over the weekend and really enjoyed it. It's short at about 85 minutes but those 85 are jammed packed. There's pretty much no filler and no let up in the movie. Pretty much the entire thing is at battle stations. It also had great bass (one of my rating criteria ) if you have a capable system. TR devices are a big plus with it.
Wasn't bad. It didn't blow me out of the water (wakka wakka!) but I was entertained. Yes, being at battle stations the whole time and the short length were quite effective.
