THOR

Kenneth Branagh did a nice job with the material.  Surprisingly, he showed a strong sense of humor that was prevalent throughout the film.  I love Kat Dennings line, after they hit Thor, about how it's legally Portman's fault.  I love the cutaway to Lady Sif and the Warriors Three immediately after Skellan Skarsgard states in despair that they need proof.

Chris Hemsworth is perfectly cast as Thor.  He nailed it.  He had a regal presence.  Natalie Portman is amazing.  She's able to generate screen chemistry with anyone. 

The film falters though whenever it leaves Earth.  Comic book movies do best when they're tied to our reality.  GREEN LANTERN spent too much time on OA.  THOR spends too much time on Asgard.  The superhero aspect already strains credibility.  To make it more palatable, you must tie it to everyday Earth, grounding it to our sensibilities, making that hero aspect real.

Branagh brought The Destroyer to life.  However, his battle with Thor was underwhelming.  That needed to be much more fierce and dynamic.  Branagh needed to showcase Thor's abilities.  The film needed a whammo here.  Something that would've left us speechless. 

Thor's a hard character to translate.  You have to get the tone just right.  After all, he's a god.  Branagh did as good a job as can be done.
