I’m not a comic book fiend, so my feedback on Thor is purely from a place of looking at the film as a stand-alone, not as a reference to the comics.
I would rank this film as “Worth Your Time, But Not a Must See.” Unlike the hot $200million mess of the Green Lantern that is about to be released, this film is not overly digital. The visual effects integrate well with the “real life” settings allowing you to just be absorbed into the story line rather than contemplating how many render farms they needed to produce the effect (which is what I think when I see the Green Lantern preview).
The story serves as a sort of introduction to the character as part of a series of films leading up to the full team Avengers film later, so the plot strikes a balance between action and character development–of Thor, that is. Natalie Portman’s character is sadly flat like many female side love interests. Kat Dennings has hilarious delivery of her lines in her side role. I hope this leads to more opportunities for her to be cast as her career has been growing over the past 5 years.
My only critiques of the film are that the first battle feels a bit rushed in the plot line for me, though folks who are big action fans might not mind this so much. There just wasn’t enough character development that early in the story for me to be much invested in it other than some muscle flexing, which doesn’t hold my interest. But after that it was pretty solid and the dynamics between the brothers and father began to emerge.
I also hoped that the sound design would be more interesting and found myself wanting more bass-y thumping and whirring winds from the massive hammer. The kind of sounds you don’t forget, like the deep base of the dinosaur footsteps from afar in Jurassic Park.
