Rocky 5 is underappreciated IMO. I like how it is back to family and character building again. Rocky retiring with brain damage is really sad and to lose all the money which of course does happen. It had moments with Adrien and with Paulie and even a glimpse of Mickey, it still had the formula. The only weakness really was the street fight to finish it. Rocky 4 was sometimes like an advert for holidaying in the Russian wilderness, but still a very good fight, though silly East against West grandstanding. Rocky 1 is just a perfect film IMO. I love everything about it.
