I found he lacked variation and screen presence in his performance which is somewhat understandable because he was still green-behind-the-ears at that point.
Elijah Wood, for example, in the earlier films put in a far more nuanced and realistic performance and, fundamentally, his experience showed.
I do have another issue with the film, but this is a general annoyance I have with most action films, and this is : slow motion.
I loath slow motion filmmaking in action films. It's gratuitous. Its eye rolling. It's lazy.
There to put more emphasis on the emotional weight of a scene when in fact it, more often than not, comes across, ironically, as shallow ,cold and over stylized.
I just hate it so much.
