OK, folks. Here's my brief review of Avengers
I've tried to identify exactly why
it works (instead of just saying "it's awesome"). A sample:
Why does Joss Whedon's The Avengers work? Because it does: brilliantly.
(Yes, it works as action, not as drama or art-house. If you want slow existential agony or impressionistic vignettes, go elsewhere.)
It can be summed up with one word: 'balance'.
Whedon - the wunderkind behind Buffy and Firefly - clearly knows how to deliver action. The Avengers, as with the other outings in Marvel's comic franchise (Iron Man, The Hulk, Thor, Captain America), is a beautiful balance of CGI artistry with old-fashioned bodily performance.
All the leads obviously trained exhaustively to fight, jump, fall, roll and generally look physical. It looks palpable. Their performances blend beautifully with the CGI, which amplifies their physicality, and provides them with fantastic enemies and weapons. Take, for example, the fight between Thor (Chris Hemsworth) and Iron Man (Robert Downey Junior).
