I just went through the Star Wars trilogy again. Some thoughts, mainly on ESB.
1. Funny that Han set up some kind of shelter to camp out on Hoth, but they never showed it. Boy, they must have needed ALL the dough they could spare for special effects.
2. This giant creature that lived in the asteroid, and tried to chew on the Millennium Falcon - how hard must that sucker have been, to live in vacuum?! And so it had some kind of atmosphere inside its belly, in which they could walk around, lightly clothed? 
3. Why is Storm Trooper armor so bloody useless? 
4. Why can't they ever hit the Millennium Falcon?
5. When Luke and Vader are fighting, and Luke gets sucked out the window, is it a little odd that Luke is able to breathe and remain conscious out there? I know it wasn't vacuum, but...
6. Leia kissed him, even though she'd somehow always known he was her brother. 
7. Ewoks are so cuuuute. But they eat human flesh.
8. And finally, Billy Dee Williams. What a corn-ball.
1. I distinctly remember a scene of them getting rescued in the morning, with Han popping out of a snow-covered shelter as snowspeeders whent overhead and he waved at them. No interior shot of it.
2. No way of explaining that one, I agree.
3. Storm trooper armor is actually pretty good ballistic/fragment armor, but there's not much that's man-wearable that will resist a blaster. Just like today, where full rifle-proof body armor is in the SAPI plates, but too cumbersome/heavy to wear everywhere.
4. They do hit the Millennium Falcon
a lot. However as a small courier/pocket freighter it's larger than single-seat fighters, and has proportionally more powerful shields and deflectors. (TIE fighters, the basic model anyway, in contrast are a quantity vs. quality argument and have no shields at all...) Also, the Millennium Falcon is indeed
FAST. If you've played any of the X-Wing or TIE-Fighter sims for the PC where the Falcon makes an appearance, it is incredibly fast and slippery due to all of Han Solo's modifications. It's even faster than the Alliance A-Wing, or the various advanced TIE models. If it keeps turning, it
might stay in the dogfight area to get shot at, but you'll never actually catch it in a flat-out run.
In one TIE-Fighter sim mission where you're supposed to catch the Falcon, you've got about 10 seconds to do so from the start of the mission before it's out of range and it disappears into hyperspace.
Also, IIRC, there's a picture of what the original stock ship from the factory looks like and the cockpit is in the center between the two gapped winglets. So Han Solo has had some serious modifications to move the entire cockpit over onto the side like he did. (Presumably more room for engines/gear...)
5. Might have been part of a force-throw by Vader, or a Force-jump by Luke to escape. In the Prequels, you see more examples of how the Jedi are willing to jump/fall many stories and control their fall with the Force.
6. The family that lays together... stays together...
7. Ewoks = FAIL. Should have been Wookies, and the battle take place on Kassyaak or whatever it's called.
8. The pimp is strong with that one...
