So, clarification on the anti-hero: It's a character, generally the main character but definitely a sympathetic character, whose moral code would in any other circumstance cause you to abhor them. Murderers. Drug dealers. Mob bosses. General jerks who are mean to everybody.

Indy is a womanizer, and he can be a jerk, so those are unhero-like qualities. He's not the anti-hero that Tony Soprano or Walter White is, and whether or not he meets the qualifications of a true anti-hero could probably be the subject of long scholarly debate among people with much more literary expertise than I have.

I'm not sure I would include Anakin because he wasn't already evil when he was the protagonist. He's a bit arrogant, maybe, which is his downfall, but every protagonist has weaknesses, and that doesn't make every protagonist an anti-hero, even when we know that they'll be a bad guy at the end of the story. (That's just good dramatic irony.)

Look at it this way: A true anti-hero would make someone raise their eyebrows when you tried to explain how awesome the book / movie / show is. "No, seriously, it's about this chemistry teacher who manufacturers crystal meth on the side, and he's great! You'll love him!"
