Was not that impressed. He was okay (maybe if I watch again he'll grow on me). Didn't spot any Shatner resemblance. Comparisons with Harrison Ford as Indy are way off. I think Chris Pine would be better in that part, e.g. the bar fight in ST09.
I like Pratt but his voice is way off for Kirk. He voiced Emmit in lego movie not Kirk level. Pine is solid but the script hasn't lended him to shatner esque level
Hoping he has a Shatner like speech w Krall at end
