My opinion of Mazzello's acting in 'The Pacific' was lukewarm at best...
...until Episode 9 came out.
Having read the book written by the real Eugene Sledge, I think I had constructed a pretty good picture of the young Sledge and knew what Mazzello's task was as an actor for this series. In all honesty, the first few episodes he was in were somewhat of a disappointment for me.
Then came Episode 9. For whatever it is worth, I think Mazzello nailed the role of a decent man turned bloodthirsty killer. The Sledge in Episode 9 is a man who has truly learned the lesson that all the things he once held dear about humanity have absolutely no value is the sort of combat he in which he finds himself immersed. What is more, Mazzello does not appear to need any lines to communicate that he has entered an animalistic, kill-or-be-killed state of mind. One look at him and you know exactly what he is thinking.
For my money, the great performance of the series remain Malek's Snafu, but on the strength of Episode 9 alone, I believe Mazzello has earned a great deal of respect and I hope that we get to see a lot more of him in the future.
