I was forced to watch a couple of movies by my friends after they found out I hadn't before. It felt like such a waste of time. I thought the plot sucked, while the characters and the universe weren't interesting. On top of that, they didn't even try to make it realistic. It's like a cheesy action movie in space. It was one of the reasons I could never get into sci-fi, until I discovered Mass Effect and realized some sci-fi plots can be amazing.
Then saying that out loud always felt like I'm committing the greatest sin. A bunch of people always seem to be talking about the newest Start Wars movies and then there's me, apparently committing blasphemy.
Yet nobody could tell me why they even like the series, just "because it's Star Wars!". For a lot of older folk that could be nostalgia - getting a new episode of a movie that really was a big thing to them back in the days, and I can totally respect that, as I have such series too. I just don't know why so many other people jump on the bandwagon without the movie really doing anything for them on its own, yet everyone has to see it.
