D9 shows the epitome of neo-colonialism and its different shades and possibilities. True racism, humans v non human, shows how bad humans can be to other races. Stylistically follows the "Cloverfield" verite flavor that many don't like, get or feel sick after watching. It works here for immediacy and tension.
IB is QTs play with languages and counter narratives. QT stages several high tension scenes with the usual brilliant camera work scanning great actors at play. It does just feel like it is all a game to all which only adds to our collective numbing in the face of violence. Beautiful, rich and satisfying. Like the strudel they eat in one scene, we need to wait for the cream, and QT delivers
Go see them my friend
