Rocky II vs. Logic

I am introducing my son to the Rocky series of films (as one does).  The first remains just awesome in every way, but that second film has some insane film logic as though in writing the film, the screenwriter completely forgot what the characters did the scene before...

• Apollo challenges Rocky to a rematch, but Rocky has an eye injury so he retires.
• Apollo calls Rocky names so Rocky says I will fight again, but Adrian doesn't approve. Apparently Rocky never heard of "sticks and stones...
• Because of Adrian, Rocky doesn't really train. Because what better way to demonstrate your manhood to Apollo and make your wife happy then by going into the ring and suffering a debilitating injury in the first round.
• Then Adrian goes into a coma, comes out of the coma and tells Rocky he should fight.  Comas apparently help people come to irrational decisions.
• Rocky trains really hard and works on his speed.  We know this because he can catch a chicken.  Mickey tells us how fast he is.
• Rematch arrives and is 14 rounds of Rocky getting pummeled because he is not fast.  Exactly the opposite of the thing Mickey told us he was.

To sum up: Rocky won't fight, he will fight, Adrian doesn't want him to fight, he totally should fight, Rocky needs to train to become fast, he is not fast at all. And I won't even get into the brilliant "fight right-handed for 14 rounds while getting beaten to within an inch of your life, then switch to southpaw when you can barely stand and immediately win the match" strategy.

So this film is basically a whole lot of filler that means nothing just so we can get to the fight.  Nostalgia had me remembering Rocky II as okay.  But this is a BAD film.
