“It’s not just the best Marvel movie to date (although it is that), and it’s not just in the very top tier of superhero movies (although it is), but it’s one of the most all-around satisfying summer blockbusters since God-knows-when.” -Oliver Lyttleton, The Playlist
“As written and directed by the ever genre-savvy Whedon, it’s a clean-burning, six-cylinder entertainment that exudes discipline in every particular, from the script’s balance of sincerity and self-effacing humor to the well-integrated visual effects to the keen sense of proportion that governs the ensemble. Whenever the possibility of boredom or excess rears its head, Whedon finds an elegant solution.” --Justin Chang, Variety
“As creatively variable and predictably formulaic as the Marvel films have been, this one will not only make the core geek audience feel like it’s died and gone to Asgard but has so much going for it that many non-fans will be disarmed and charmed. This is effects-driven, mass appeal summer fare par excellence, that sought-after rare bird that hits all the quadrants, as marketing mavens like to say.” --Todd McCarthy, THR
“Iron Man and Captain America probably get the most screen time (or at least the most focus). And while Whedon and the funny and clever Tony Stark seem made for each other, I was very impressed how he handled Captain America, who is a far more straightforward and unwaveringly noble fellow than Whedon – who prefers his characters to be a bit more ambiguous and flawed — is known for, but one he handles very well, as Cap takes on the leadership role he was destined for.” --Eric Goldman, IGN
“It is not often you can say this, but The Avengers is one $200 million-plus event flick where not a single cent has been wasted. The special-effects work is spectacular, especially during two truly awesome set-piece battle sequences.” --Leigh Paatsch, The Daily Mail
There are a few complaints, but mostly it is very positive. Of course the distributors are making sure there advance screenings have people inclined to like this movie, but this is definitely a good sign.
