first of all, i think wanted is one of those films that's going to be a bit of a guilty pleasure for me. the plot is ludicrous, but it's so much fun to watch that as long as you don't take any of it seriously, you should have a lot of fun with it.
performances are spot on. james mcavoy in particular who i've become a huge fan of in recent years, and i think he's become one of our finest young actors is terrific, although you wouldn't neccesarily picture him as an action hero, he does a terrific job. angelina jolie is excellent, one of her best roles in a long while, and morgan freeman, who let's face it, is incapable of giving a bad performance ever, no matter what he's in is very sinister as the head of the group of assasins.
plot as i said is ludicrous, and although it is visually stunning it does seem to rip off the matrix movies, and the russian director's own nightwatch and daywatch movies. in short, it's big, loud, dumb, and very enjoyable and one of the best pure action movies in years.
