I did like the music. I did like the FX. Did pick up on the Scott Pilgrim, I'm just not in lesbians with this video.
I think the mixed genres didn't quite mesh right. It was a bit too kitsch for garage, which I think should have a sort of apathetic anger, while the uke and the Hawaiian shirt were a bit too wink and a smile. On the other hand I didn't get the uke feel from the instrument.
I think if you want to do this you have to make it feel like you're forcing the cute puppy (ie uke) to bark, or go the other way and take a garage song and camp it up all the way.
The Ukulele Orchestra of Great Britain mashed genres perfectly with Smells Like Teen Spirit.
I'd like to see it again going one way or another.
Of course you could always tell me to sod off.
