I couldn’t care less about someone’s accent. It’s irrelevant to the fact that if you’ve seen a lot of American WW2 films then you’ve seen everything that SPR does except the latter does so with a higher budget and much more self importance. The most potentially interesting element of the film - that Private Ryan himself was just an ordinary guy and probably not worth all the superior soldiers who were killed trying to save him - seemed to be lost on the filmmakers.
I would agree that Band of Brothers is actually a superior work, than Saving Private Ryan. But it was the success of Saving Private Ryan, that made Band of Brothers possible in the first place.
