Maybe. He wasn't the casting director, as far as I'm aware, nor director or producer. So laying all blame on his shoulders seems a bit singlemindedly petty to me.

Its easy to say in hindsight that we were wrong in any action from the past. The problem is that its the past, and changing it is currently beyond us.

I dunno, I think he did well at portraying the character. He made me dislike the character. We aren't supposed to like Anakin; he's this deeply flawed, messed up person that follows the bait of the dark side like he had no mind at all.

That's what the character was written as.

But he managed to do that believably. The way he delivered lines, his body language, it really read like this damaged kid that got thrown into being some kind of savior and went batshit over time.

If anything, I would say that Ewan did a little too much over-acting in the prequels. He's a really solid actor, but he leaned hard into emoting heavy as a way to denote that obi-wan is normally trying hard to not emote. It worked with the way things are written, but it's a fairly obvious choice that doesn't scan as well as most of Hayden's scenes where he's pushing.

Then again, it's all a matter of opinion, and yours is valid :)
