Guido! We Were Soldiers is possibly THE worst war film I have ever seen bar none!
As a separate aside - as usual when this thread crops up on a quarterly annual basis, it is littered with people listing films that they like rather than films that could in any way be considered 'underrated'
Agree it shouldn't be on this thread (see also Downfall above). Even though it's got more glaring historical errors than just about any other WWII film, WED is still a stone cold classic. I watched two British 70s horror films recently - Witchfinder General and Blood on Satans Claw, and...
End of Watch, the LA police film with Jake Gyllenhall is an underrated film imho.
Also the Boston bank heist film The Town with Jeremy Renner and Ben Afflek.
Harsh Times with Christian Bale another.
Any film with Mikkelsen is usually decent, a lot of his Danish films are worth a watch, but as you say, people unfortunately don't on the whole do subtitles, which is a shame because most foreign films blow English language films out of the water imho.
