I'm pretty sure we've clashed on this subject before. I've defended X3 for the most part. Having pointed that out, I completely agree that Penn came off as an ass in that interview. It goes to show you the level of his intelligence. Why re-hash the X3 stuff? There's NO point to it. Why lie and say he and Kinberg were truthful when they were answering fan questions? All he did was piss off fans like you who hate the film and alienate fans like me who were cutting him some slack.
I took part in that fan xverse forum. Kinberg and Penn flat out lied, exaggerated and misled fans in those question and answer sessions. Now, he states that he was truthful and that fans can't deal with it? Again, what's the point, especially since he's mistaken?
The more he talks and the more you break down his work, the more I hope they take Avengers away from him ASAP.
