Like Bandit said, time for me to join in =]
I love, love, LOVE, LOVED this movie!
I left the theater xmas eve last year so blown away, I couldn't believe it. I thought "hey: i'll like this. I loved Tron, why not!?"
I believe not having unrealistic expectations is key to accepting a movie like this when you think of the amount of time it took them to make a sequel, and what kind of changes and impact that has on a story and how you have to detach yourself a little bit from what you're so familiar with (ie, the original film).
I was obsessed after first viewing. I saw Legacy 3 times in the theater, and wanted to go back for more but it stopped showing! =] I immediately got the soundtrack and listen to part or most of it literally almost every day since I got it. Loved the story, loved the dialogue, the references to the first movie, loved the actors/acting. The design/look of everything in the grid was just stupidly amazing.
But for me, what fascinated/intrigued/made me love it in a whole different way apart from all other films I love, were the COSTUMES! I've never thought about cosplaying, or costume making, or props or anything like it until Legacy. Making my costume, and finding this site, and talking to all the nice people on here has been such a fun adventure. I wouldn't be here if it weren't for the awesomeness of Legacy =] I owe it all to Legacy.
And I think I can speak for others that found their way here solely because they thought it was just as amazing as I did.
Not to mention, going to cons and Halloween parties this year in my costume, and the massive reactions and compliments I got from it made me feel so out-of-this-world euphoric, it's hard to articulate it in words. I owe that feeling not only to everyone on this site that helped me and inspired me along the way, but most obviously, all the talented people that made Legacy happen.
THAT'S how much I thought this film was the best movie I've seen since I saw Star Wars when I was 5.
