Avengers: Age of Ultron Early Buzz

Avengers: Age Of Ultron is bigger, more complex, darker, more action packed than the first film, but ultimately not as much fun. — Peter Sciretta (@slashfilm) April 10, 2015

AGE OF ULTRON is a blast and there's a ton of cool Marvel surprises! — Silas Lesnick (@silaslesnick) April 10, 2015

AGE OF ULTRON: Liked, didn't love. A lot more bleak than the first. Excellent banter, great action, SO MUCH HAPPENING. — Ben Pearson (@benpears) April 10, 2015

While #Avengers felt like a bookend to Phase 1, #AgeofUltron definitely feels like a conduit of things to come. That being said, it rocks. — Terri Schwartz (@Terri_Schwartz) April 10, 2015

By all means @Marvel is still firing on all cylinders – was fun to geek out to Avengers: Age of Ultron – a highly entertaining follow-up! — Jeff Goldsmith (@yogoldsmith) April 10, 2015

AVENGERS AGE OF ULTRON is loaded with insane action, great character moments, and funny dialogue. Joss did the impossible again. — Steven Weintraub (@colliderfrosty) April 10, 2015

Important to note AVENGERS AGE OF ULTRON is a completely different movie than the first one. And that's why it works. — Steven Weintraub (@colliderfrosty) April 10, 2015

Yep, it was awesome. Sensory overload. — Amirose Eisenbach (@Amirosie) April 10, 2015

Big love for Avengers: Age of Ultron. Tons of fun, awesome action, and fantastic performances from all — Eric Eisenberg (@eeisenberg) April 10, 2015

#AvengersAgeOfUltron is darker, weirder and more emotional than the original. It's also the thrill ride to beat this summer. — Drew Taylor (@DrewTailored) April 10, 2015

Just saw AVENGERS: AGE OF ULTRON. Soooooooo many characters and soooooo much going on, I can't believe it's coherent, let alone so fun. — Mike Ryan (@mikeryan) April 10, 2015

And out of all the AGE OF ULTRON chaos, somehow Hawkeye gets the best role in the movie. AND the best line of the movie, maybe the series. — Mike Ryan (@mikeryan) April 10, 2015

One more: Spader's Ultron so much more snarky than I thought he would be. So, yeah, he's basically James Spader. — Mike Ryan (@mikeryan) April 10, 2015

Avengers 2 is both an amazing sequel and a fantastic setup for the rest of the MCU. So nerdy in the best possible way. — Mike Sampson (@mjsamps) April 10, 2015

Also, the usual Avengers supporting players stand out this time. Black Widow kicks ass and Hawkeye has the best lines. — Mike Sampson (@mjsamps) April 10, 2015

Whedon stuffs Avengers Age of Ultron with an impossible amount of great geekiness. Sometimes it feels like too much, but he pulls it off! — Kevin P. Sullivan (@KPSull) April 10, 2015

Avengers 2 is way more fun and great than the trailers let on. — Meredith Woerner (@MdellW) April 10, 2015

Avengers: Age of Ultron: An entire "phase" in Soylent brick form. More nerd plot, more spectacle, more sarcasm. Feeling good dizzy. — Matt Patches (@misterpatches) April 10, 2015

Again, we’ll keep updating this space as more reactions come in throughout the evening. Keep it here.

Avengers: Age of Ultron opens May 1.

Marvel Studios presents “Avengers: Age of Ultron,” the epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth’s Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance.

Marvel’s “Avengers: Age of Ultron” stars Robert Downey Jr., who returns as Iron Man, along with Chris Evans as Captain America, Chris Hemsworth as Thor and Mark Ruffalo as The Hulk. Together with Scarlett Johansson as Black Widow and Jeremy Renner as Hawkeye, and with the additional support of Samuel L. Jackson as Nick Fury and Cobie Smulders as Agent Maria Hill, the team must reassemble to defeat James Spader as Ultron, a terrifying technological villain hell-bent on human extinction. Along the way, they confront two mysterious and powerful newcomers, Wanda Maximoff, played by Elizabeth Olsen, and Pietro Maximoff, played by Aaron Taylor-Johnson, and meet an old friend in a new form when Paul Bettany becomes Vision.
