I watched "Overlord" for as long as I could take it (about an hour). I just couldn't finish it.
First, I can't imagine there was any paratrooper unit commanded by a black officer or had a black paratrooper in its ranks on d-day. While there was apparently an all black US paratrooper (555th) battalion they never served overseas according to wikipedia. I know many films have historical inaccuracies, but this was pretty blatant (and of course I'm not saying there shouldn't have been or it was right, just that there weren't). OK, I could have got by this if the movie was really good with a captivating story, but... it wasn't. And:
The final straw was a French kid who liked baseball and had a baseball bat and ball. Of course US audiences wouldn't think anything of this (completely normal in Anyville, USA) but: REALLY? I mean REALLY? It's a bit like a British made film having British paratroopers drop in on d-day and they happen to go into a French village where the first kid -quelle surprise -they meet loves cricket and has a cricket bat and ball... yeah, right.
I'd actually read fairly decent reviews about this movie, and one reviewer said the second half really warms up in a b-movie way. I just couldn't do it and turned it off. 1 out of 10.
