I'm younger than Luke would have been and even I know that regardless of how scared you are, you're much more likely to survive when fighting a Wampa with one-arm using a lightsaber than you are when wandering about in a freezing blizzard. It would certainly have been kinder to the Wampa to finish it off than let it starve to death because its one arm would mean that it would have a much harder chance of making a kill. Sometimes you have no choice but to fight because it's a 'kill or be killed' situation
You don't really know how you would act in such a situation unless you are actually in it. It's easy to make plans and predictions from the safety of your home behind a computer screen. Luke is injured, panicked, confused and very likely disorientated; sound judgement can very easily go out the window in such a situation.
You use the phrase "kill or be killed", but the more apt phrase is fight or flight. Obviously he made the wrong choice, but it is extremely understandable given the circumstances. People often behave in very erratic ways when put in very stressful situations.
Possibly the weakest and most stupid part of the whole film is Han prancing along exactly in the right direction to save him just out of pure luck, when there would be such a small chance of that happening normally in the snow, makde even smaller by the blizzard itself.
It true that the chances are remote, but that scene is more about Han not giving up on his friend. Also he is not just prancing around, he is using a scanner (even if the range is limited by the storm). Also, he is working off of Luke's last known whereabouts.
If you want to be a Jedi, like Luke does, you can't think with your heart all the time. While you should show compassion and love, you have to show it to everyone in equal measure and not let your love turn into an obsession, thus turning you to the Dark Side and making you much easier to defeat. Somehow it seemed to work out all right anyway because Luke was a much better character in 6.
That is actually one of the major themes of the movie. Luke being tempted by the dark side is an important aspect of the film. Just as Anakin was turned to the dark side (via love), the movie explores Luke's journey on the precipice separating the light and dark sides of the force. The cave scene on Dagobah is a direct illustration of this. Then in episode 6, this theme is concluded when Anakin is brought back to the light side of the force because of his love for Luke and Luke's love for his father.
Once again, you have to consider that Luke is still at a very early stage in his training and that his training began at a much older age than normally permitted by the Jedi.
You would have had a much better chance of rescuing the prisoners than Luke did on his own. Vader wouldn't have had that much of an army on Bespin because otherwise the population would have grown riotous because they would feel too dominated - he would probably just had a couple of battalions of Stormtroopers with him, and we know how easy they are to kill. In fact Vader is the only decent combatant in those Imperial Forces, because Boba Fett was even more useless than the Stormtroopers, and the whole Rebel Alliance could easily have defeated those forces. Remember that Cloud City wasn't that big, Lando and his wing guards would have been able to help out and also the Alliance was much bigger than it was at the time of Rogue One and IV, because as soon as people heard about the Battles of Scarif and Yavin, they realised the Alliance had forces powerful enough to tackle the Empire and support for them grew as a result as Palpatine's illusion of tyrannical security began to lose its grip. The Alliance would have had lots of extra blokes join them as a result.
First off, we have absolutely no idea what kind of forces the Empire has in orbit around Bespin or nearby. To risk your entire fleet in what very well could be (and actually is) a trap is a poor tactical decision. The Empire typically outguns the Rebel Alliance by a fair margin, so a direct assault is rarely the best option. Secondly, if the Rebel Alliance did show up in numbers and actually managed to outmatch the Empire, then the prisoners might be executed, as Vader and company cut their losses and flee.
Anakin had his hand cut off by Dooku but you didn't see him burst into tears about it - he gritted his teeth and took it like a man. It took a load of molten lava and having both his legs sliced off to make him cry out like that. I'd say certainly Mr. Hamill was overacting in that scene. Also, let's face it - if Vader hadn't realised Luke was his son, he'd have killed him in about five minutes - Vader clearly wanted to spare him, both out of love for him and to try to tempt him to the Dark Side.
Once again you fail to take into account that Anakin has SIGNIFICANTLY more training and experience than Luke. It is an extremely unfair comparison. In regards to Vader sparing Luke, in that we fully agree. If Vader wanted him outright dead, it would have been a very short fight.
That's a bit hypocritical - you don't give Jar Jar any slack at all. You may think it's completely different, but it's just the same - you think Jar Jar's annoying, I like him. I think Luke in 5 was annoying, you like him. I'll only cut Luke some slack if you cut Jar Jar slack.
Hardly hypocritical, Jar Jar is perhaps the most hated Star Wars character of all time. On the flip side, episodes 5 and 6 are largely considered to be the best in the series. I'm not trying to change your personal opinion, but the numbers my friend are not on your side.
