When the POV started I thought, "Wow! Looks like I'll be eating my words!" But everything went downhill once it went, well, downhill
Halfway through Let It Go, it feels like the ride just loses all its momentum and it ended with me thinking, "Why are we here?" It felt like they were trying to craft a story at the start, but then they forgot where it was going while they were telling it.
That being said, I'm kind of obsessed with the AAs and I love how they presented the music. Having different characters sing the songs (and adding harmonies??) was a pretty perfect idea: make it new, while giving people what they already love. Kudos on those aspects!
