I am typing this from my phone, so please forgive any kind of typos. :P
I thought the play was entertaining dinner theatre and nothing more. The highlight was honestly the set, which was incredibly cool and impressive. Metcalf was also great, she had the character down but she seemed to be fumbling her lines often when I saw it (Wednesday night). Willis was not good. I wouldn't say he is giving the worst performance ever but his delivery is very wooden and he did nothing to make me care for his character. I also thought the finale was quite anticlimactic and they could have made it a bit more theatrical.
I also did the stage door and if it's like this every night, I would suggest staying away. I will start this out that no, it is not an actors job to sign or talk to fans. I know this and 100% agree with this statement, so please nobody jump down my throat. I braved the door for Metcalf, who came out very quickly and when people clapped, she looked literally disgusted and ran away as quickly as humanly possible, not even acknowledging her fans with as much as a wave. Then Rumer Willis came out and got in he dads car, so everyone was going crazy that they knew he was going to come out. When he did, he came to me first (I somehow was at the front of the barricade) and I told him the show was really well done and he didn't do much as smile at me. He then signed for maybe four other people and said "I'll be right back guys, I promise! Don't worry!" And then ran into his car. I don't really see the point in blatantly lying to your fans like that, especially considering the crowd was surprisingly well behaved (at least up until that point, people were not happy after he said that and ran away). Just was just of a surreal stage door experience. :P
