My view (FWIW) of the show-
My hat is off to the network for doing this live production. I worked at a broadcast tv station in the top 3 major market for 35 years (just retired). People (not in the industry) really can not appreciate how big a task it is to do a show like this. Months of rehearsals, set-ups, etc. There is no feeling like working on a show like this-your adrenalin is always pumping when you go live! Anyway-my views--
1-Audio. As has been previously mentioned, the person who was Senior Audio on this should be banished from doing audio on any future production! The hiss that was heard in the show was absolutely inexcusable! They had months of rehearsal time to work out any kinks and to get this right. They probably didn't use booms for micing. Booms, for the most part, are pretty much an obsolete mechanism-at least in tv production. When I first started in the industry, "booming" still existed and we had people that knew how to do it properly. Most of these people are working films and/or retired now. Wireless mics were not used on this show-none were visible nor were the belt packs (telltale bulges under clothing). So, IMO, they hung mics from the gridwork. Which, when done correctly, works great. But, to me, it sounded like they used "omni" pattern mics. Then, when voice levels were too low, they just hiked the faders up to compensate (I didn't notice any AGC "pumping"). They should have, perhaps, used a hypercardiod pattern type mic or, for close-in spots, perhaps a "shotgun" tight pattern style mic. And, they couldn't use an excuse, such as, "There were too many mics to control". On modern audio boards, you can set up e-mems for different scenes. By doing that, you can preset each scene. And, then, just call up each scene in literally less than a second. It's a marvel to watch how a board can be changed by e-mems.
2-Video shading-I think a pretty good job was done in this area. Using different color temperature camera set-ups/lighting to differentiate between indoor/outdoor sets looked well-done. All cameras were equally balanced and was very evident.
3-Lighting-Also a well-done here. Instead using using "flat" lighting, extra time was spent adding texture to the different sets. And, as above, the use of different temperature gels really added.
5-Switching/directing-Fairly well-done considering this was an actual live show. Things can get real hairy real fast in this type of production. It appears the A.D.'s did a good job calling out upcoming shots for the director/switcher.
6-Makeup/wardrobe-On a live show, changing wardrobes can really be a mess. That was not apparent here. A good job was done.
7-Talent. I liked Carrie's singing abilities. As to the acting, not too bad. But could have been a little less "stiff". Frau Schraeder's character I thought was well done. The Captain's character seemed a little "stiff" to me. But, he could sing well. The Children I thought, overall, were well done.
These are just my thoughts, which aren't there to persuade anybody else. Once again, I thank the network for doing a live show like this. In times past, this was attempted more often. It was great watching live TV like this. And, I think Senior Audio should be demoted to being a "gopher" for the stage hands.
