Even before he was cast in the role, I always thought that Eisenberg was a one trick pony. Let's face it; his entire career is based on him playing the same anxious, socially awkward character in every role. The Squid and the Whale, Adventureland, Zombieland... Eisenberg is literally the exact same in every film. They might as well have given his character the same name in each. I'm not saying Eisenberg is a bad actor per se, but when Batman Vs Superman is eventually released, I won't see Lex Luthor on the big screen. I'll see Jesse Eisenberg in a bald cap. The biggest problem here is that Eisenberg's mannerisms and tone of voice are very distinct, so even if he does pull out a strong performance, all I'll be thinking is "Damn you Zuckerberg! Andrew Garfield deserved some credit!"
