Filmmaker Joss Whedon has more than enough on his plate at the moment, as he gears up to start shooting The Avengers: Age of Ultron soon, and he has the new ABC series Marvel's Agents of S.H.I.E.L.D. debuting next month.

Regardless, the director took time out of his schedule to reveal that he isn't a fan of Star Wars: Episode V - The Empire Strikes Back's ending, where Luke Skywalker is revealed to be the son of Darth Vader, and Han Solo is frozen in carbonite.

"Empire committed the cardinal sin of not actually ending. Which at the time I was appalled by and I still think it was a terrible idea. Well, it's not an ending. It's a Come Back Next Week, or in three years. And that upsets me. I go to movies expecting to have a whole experience. If I want a movie that doesn't end I'll go to a French movie. That's a betrayal of trust to me. A movie has to be complete within itself, it can't just build off the first one or play variations."

The filmmaker did reveal that he thinks Star Wars: Episode V - The Empire Strikes Back is one of the few sequels that were done right, along with The Godfather: Part II, despite his issues with the ending.

He was also asked about his thoughts on The Twilight Saga, since he wrote the script for the 1992 movie Buffy the Vampire Slayer and created the 1997 Buffy the Vampire Slayer TV series.

"A small part of you is like: 'Well, you know, I did that first. I liked that band before they were popular.' The thing about Buffy for me is - on a show-by-show basis - are there female characters who are being empowered, who are driving the narrative? The Twilight thing and a lot of these franchise attempts coming out, everything rests on what this girl will do, but she's completely passive, or not really knowing what the hell is going on. And that's incredibly frustrating to me because a lot of what's taking on the oeuvre of Buffy, is actually a reaction against it. Everything is there - except for the Buffy. A lot of things aimed at the younger kids is just Choosing Boyfriends: The Movie."
