This is a movie featuring the indonesian martial-arts Pencak Silat and starring Iko Uwais and Joe Taslim and I think they should have named it Raid: Relentless 'cos the fighting and violence is brutal and pretty much non-stop, check out the clip for a 4 min example of what the rest of the 100min movie looks, and sounds like. As to plot; script and character developement - there's no room to fit any of that in.
