Not to me; I loved that movie! It was the first (and only movie) that I saw with John C. Reilly, and I was shocked with how good he was since everything he was in never appealed to me. Everyone was great though, and it was very true to life. I love intimate movies like Carnage, Repulsion, Rear Window, The Conversation, Sunset Drive, and Locke. There's so many awesome movies with characters confined to a single room. That's one of the reasons why "The Fly" was one of my favorite Breaking Bad episodes. I'm always a drama guy first...except when it comes to BvS, I'm making an exception because Batman LOOKS AWESOME!
I had seen JCR in other movies as well, but mostly as the "funny guy", and not much more. Here he was really good, and I loved how he slowly dropped his "Flanders" act to reveal a machisimo dude. Waltz was great as the ******* as well. As for the rest of the films you listed, I've not seen them yet, but I have them on my "to watch" list, especially Locke (I've been on a Hardy kick these last few days, and I've watched pretty much all his major stuff, from Child 44 to Legend and Drop).
Fun Fact: I only found out about the movie from searching the "Carnage" tag on Tumblr. I was looking for Cletus Kasady/Carnage art and the like, and I stumbled upon it. I saw Waltz was in it, so I gave it a go.
PS: This isn't exactly a "confined space" film, but it features only 3 actors, so I guess it counts. I'm talking about Z for Zachariah, which I really liked, especially Robbie's performance. I was really surprised that she played a 17 year old girl so easily, especially since her role in Wolf was a 30-something grown and confident woman. Ejiofor and Pine were great as well.
