There are obviously intentional parallels between the two trilogies. But I'd have to strongly disagree with the idea that the "main point" of Star Wars was to meet characters that would be in the next two films. In many ways this was the intention of The Phantom Menace, but when it was made, it was clear there would be two sequels.
With Star Wars, George himself said he jumped right to the middle of the story, because that was the exciting part, and he didn't know if there would be anymore. Star Wars was obviously not just a pilot episode, or having its main point to be setting up characters. It is sad to think some people actually see it as that.
Another parallels would be that we meet Boba Fett in TESB and then we meet both Jango and Boba in AOTC. Although, if this were a true parallel, instead of having Jango die like a bitch in AOTC, he would have died like a bitch in ROTS as Boba died like a bitch in ROTJ.
"Episodes II and V, Both movies put the rebels/republic in a dark time. Only difference is u may notice it a little more in AOTC. Both contain love stories."
This is a very interesting statement to me. Not that there is anything wrong with it, it is just that personally, I would have thought ESB as by far the more dark time-ish of the two.
Maybe this is do to the fact that AOTC completely failed to capture any emotional attention from me whatsoever. In ESB we start off with Luke nearly getting eaten by a wampa, then Imperials discover there secret base and attack it with over whelming force. Luke goes to meet Yoda, and proves to be a horribly impatient and a poor excuse for Jedi material. Finally Yoda is convinced to train him, and just as the training is getting started, he runs off for emotional reasons, leaving Yoda thinking, "Ah, crap! This idiot his hopeless, hope he gets himself killed before he has a chance to turn to the darkside. Guess we will have to track down the other." Meanwhile, Han and Leia spend the whole film running for their lives in a very unhealthy Millennium Falcon. They finally find a safe haven, only to be betrayed by a friend, which eventually ends up with Han being frozen and taken away, his fate remaining unknown for a whole three years (real world time). Luke flys into a trap, learns some depressing news, his father the hero is really his father the villain, and his mentor had been lying to him all this time... or maybe Vader is lying, either way, poor kids head is filled with doubt. Oh yeah, and he loses his hand and his dad's old lightsaber, talk about one bad day!
Attack of the Clones... Anakin acts like a whiney idiot, Obi-Wan acts like an annoying nagging father figure. Anakin takes off to go protect his one true love and try to make her fall in love with him by whining and killing villages of sand people. Obi-Wan goes on a very contrived and ridiculous quest to discover who is trying to kill Padme, which eventually leads him to a ridiculous bit about these long necked CG guys making a million Boba Fett daddy clones at the whim of some dead Jedi. Eventually, it is decided that war needs to break out, and the convenient news of the clone army of New Zealanders of questionable origins arrives back to the Republic, and they decide "Hang questionable origins! We wouldn't want to miss this chance to go on a crazy meaningless war, would we? Vote now, vote now!" And so war breaks out in a gladiator arena (with LFL thinking, hell, I bet we could make some pretty sweet video game levels if we had the war start in the middle of giant gladiator arena!). After TPM everyone was expecting another amazing lightsaber battle, instead we get flashbacks from Muppet's Treasure Island (Kermit with a sword, just in case everyone doesn't get it), Anakin getting his arm cut off rather anticlimactically, and the villain turning tail and running like a pansy (a character trait George found very becoming of his villains, and reused the idea to the point of cliche in his next film).
Oh yeah, and then there were the large beasts in the gladiator arena that reminded me of Ghostbusters toys for some reason... and... okay, I concede, AOTC is by far more depressing than ESB. Not so much of a darker film, but just more depressing in general...
