Agreed about 71, thought it was great. The invitation was good as well, I did enjoy it although I felt some of the acting/script was a bit strange at times.
Slightly similar to the invitation was 'coherence' (because it's set around a dinner party) which is worth a watch.
Other films I watched recently (not necessarily recent films though) which I enjoyed were: big bad wolves, ex machina, crimson peak, down terrace, room, chinatown, brick.
A couple that I didn't rate that highly (which came with good recommendations) were deadpool and the conjuring.
