I liked it. I thought it was funny and interesting. I didn't really care for the flashback to 2001 that shows Homer WITH hair. If he'd been bald, I would've been okay with it, justify in my head by saying "maybe he had a second job we didn't see." Or maybe have set it back in like 1985 or something. It's nitpicky but that's such an easy thing for the staff to not draw attention to. They could've even just put "Years earlier" on the screen. Bleh, whatever. Still a good episode.
