Got to admit, I have a soft spot for Rocky II, probably due to the fact it's the one I watched most often as a kid. As for Adrian being rubbish in it? How dare you!! Adrian in a coma probably stands as the best acting performance of Talia Shire's entire career.
The part where she wakes up, Rocky asks if he can do anything for her, and she just say's "Win", with the music building in the background and Mick (in full on Penguin mode) shouting "WHAT'RE WE WAITING FOR?" is a much simpler and far more effective moment than the forced pep talks she gives to Rocky prior to the Clubber/Drago fights.
I also don't see how II is 'full of holes'. I mean, compare it to the third one, which in quick succession sees Rocky being bounced around the ring by Hulk Hogan, discovering that his manager had him fighting deadbeats ever since his title win, being honoured with a giant statue, getting pummelled by a p****d off Mr T, stumbling back to his dressing room to witness the death of his manager, reconciling with his former arch-rival, relearning his entire fighting style, gaining super speed from a bit of skipping and swimming, running up and down a beach without even taking time to stop and laugh at Apollo's little shorts/big socks/bare midriff attire and deliberately allowing Mr T to launch bombs into his body and face until he's out of breath before going 'Aha. Only messing with ya. I was pretending the
whole time'.
