Streamed this last night from NF. I thought this was a departure for JS. The way it started I thought it was going to be his usual kick a$$ every 5 minutes or so, which is just fine by me and a big reason why I like him so much, but it turned out to be the opposite. While not a great movie, I thought it was entertaining enough that I would easily recommend this for a rental. I say rental because the NF streaming was only stereo and it almost brought my walls down. I'm betting 5.1 would sound awesome.
There's some very nasty violence in the Blitz, so it's not for the kiddies.
