Oh man, what can I say about this fic that hasn't been said already? I love the character of Sam, he's such a stuffy yet lovable old grump, and you've done an amazing job of capturing that as well as giving him more layers. His relationship with his kids and wife is so interesting, heartbreaking, and endearing all at once.
Matilda is a boss, I love how tough she is and how she doesn't take any of Sam's crap. Andrew is such a sweetheart, so adorkable! As for Hilary, I can definitely relate with how snarky she is and how frustrating her situation can be at times.
All of the canon characters are written wonderfully too. I could hear each character's voice and of course, being the band geek that I am, every scene with the Electric Mayhem was a gem. (Especially the scene where Teeth, Floyd, and Janice call Sam out for his attitude! Good stuff!) Sam and Rowlf's friendship was one of my favorite aspects of the story as well, such a funny and underrated duo!
Overall, this is a treasure of a fic and while I'm sad that it didn't really have an ending, it was such a great read! Many kudos!
