Then go watch Das Boot! If you are a big fan of the 80's original movie or the books it's loosely based on - this is probably not your thing and you'd better skip it.
Is it historical correct? Definitely not. Does it have the usual agenda concerning LGBT and female main characters, which is apparently mandatory nowadays? It does. But much more important is what else it is: it's suspenseful, entertaining, heart-warming, exceptionally well acted by the entire cast and the set and scenery is incredibly detailed and artistic. That's just perfect entertainment!
