I think the actual production was just as bad as, if not worse than, the technical side of the show.
To me, the telling of the plot itself was poor. The audience participation at the beginning was cringe-worthy, cheesy, and difficult to understand. Not to mention, it felt like a lazy attempt to shoehorn crucial exposition into a gag. Perhaps some sort of pre-recorded projection, or even a simple narration, would be more effective and less deserving of eye rolls.
The transition into the first major scene was equally awful; it was awkward, poorly timed, and didn't mesh well with the previous scene. It seemed like the show was going for something better suited for a TV show or movie, where a character thinks of an event happening elsewhere, and the film cuts to the scene he is thinking of. But played live, I don't think this worked out well.
The worst part for me was the dialogue. Maybe it was the stilted, high school drama class-style delivery, but every time a character opened their mouth I wanted to crawl inside Nessie's cave and hide. The lines were cheesy, over-the-top, awkwardly worded, and simply made my skin crawl.
I usually don't rag on performers, but as I said, some of them had ZERO acting talent and probably should not be acting. Their athletic skills were impressive, but as far as acting goes, they may as well have been auditioning for a black box play. Frankly, the show would probably be much better if the microphones didn't work at all. At least we'd be spared from the terrible delivery of terrible lines.
The conflict resolution, too, was weak. The villain isn't foiled. There's no dramatic end to the antagonist. Milady de Winter just randomly vanishes, and one of the Musketeers makes a passing comment that she may someday come back. I understand that the Three Musketeers story ends in a similar way, but--let's face it--All For One is hardly an accurate representation of the original story, so they may as well have gone for a more satisfying conclusion.
Long story short, I personally think the show needs a lot of work on both the production side and the technical side (which I won't delve into now). Until then, I'll spend my evenings in Aquitaine riding Griffon while the rest of my group watches this cringe-fest.
