I attempted to avoid spoilers aside from the tv spots, so the movie was a bit unknown to me and I had a lot of surprises in store for me.
What theories or spoilers or assumptions did you go into the movie with that were totally wrong?
--The title "The Force Awakens" meant that nobody new got Force powers ever since ROTJ, and something at the start of the movie finally awakens the power in Kylo, Rey, and Finn. That's why Finn freaks out and goes on the run. Presumably something Luke did. This means that was never a Jedi Academy run by Luke, who was mostly alone these past 30 years, and Han and Leia's kids never had powers before now.
--Luke would actually be in the story and talk
--Luke would help them infiltrate the Starkiller Base a la Obi Wan
--Rey was Han and Leia's kid. She's been living on Jakku to grow up in hiding safe from Imperial assassins.
--Snoke was Plageuis
--Kylo Ren was Luke (just kidding!)
--Leia would be more than a glorified CO sending people on missions
--Poe Dameron would be boring and stiff
--Boyega would use his natural British accent
--Von Syndow was Rey's father figure and would have more than one scene
--Captain Phasma would actually do something, contribute to the story in some way, get an action sequence, fight a hero, or actually show her damn face. There's a Funko Pop figure of her, damn it!!!
--Rey owned the Falcon.
--That bad ass scene of Kylo with the rest of the Knights of Ren, including one holding the Buster Sword from FF7, would actually figure into the present day plot.
--Snoke would look like a weird alien and not just some scared/defaced human.
