I think this was one of the many mistakes they made with the Hobbit movies. Or at least with the first 30 minutes or so of the first one, I never watched any of it past that lol
Between the goofy musical number and the bad acting I just turned it off and never looked back. Oddly enough I really enjoyed the songs in the old Rankin and Bass animated movie lol
In contrast, the early song number is the only part of the Hobbit trilogy that I didn't sleep through.
Home invasion by singing dwarfs was already hilarious in the books. That it's a quality bit of chorus singing in the film just makes it that much better, to me.
The rest of the Hobbit trilogy felt meandering and unfocused to me.
In fairness, I really desperately needed a nap the last couple times I tried to watch them.
