The release of the highly-anticipated Marvel film "Avengers: Age of Ultron" is just a week and a half away in America, and while fans are getting amped up, critics have already had a stab at the film -- and one Forbes review calls the film a "Galactus-sized disappointment."

Yikes! Could it really be that bad?

The film is reportedly looking at an opening weekend of around $215 million, so here's no denying that it's slated to have a colossal impact on the box office, regardless of any negative reviews. Bottom line, Marvel fans want to be the judge for themselves.

Forbes points out that even if "Avengers 2" "underperforms," fans are already psyched for "Captain America: Civil War."

"The only real negative if this film doesn't connect with audiences as much as the first one is a potential lessening of excitement for 'Ant-Man,' but that's a bit speculative (and that new 'Ant-Man' trailer was terrific)," said Forbes contributor Scott Mendelsen.

The author recognizes that his opinion may not reflect the consensus and "will be at worst a bump in the road on the way to 'Infinity War' in a few years." He plans to delve into more details of the film, as well as the entire Marvel film library.

So what did he think?

"'Avengers: Age of Ultron' plays like an obligation, a box to be checked off on a list before all parties move on to the things they really want to do. The story is shockingly inconsequential, both in terms of the overall Marvel cinematic universe and even in terms of stand-alone 'Avengers' movies," Mendelsen wrote.

"It hits all the marks, providing big-scale action and the required witty banter, but there is an air of artifice and irrelevance to the whole affair," he added. "The situations that occur in this fantastical sequel are theoretically world-changing and should be game-changing to the Marvel universe, yet the implications are either ignored or tossed off as if it were just another episode of 'Avengers: Earth's Mightiest Heroes.'"

"The Avengers: Age of Ultron" cast includes: Scarlett Johansson as Black Widow, Robert Downey Jr. as Iron Man, Chris Hemsworth as Thor, Mark Ruffalo as Hulk, Chris Evans as Captain America, and Jeremy Renner as Hawkeye with the additional support of Don Cheadle as James Rhodes/War Machine, Cobie Smulders as Agent Maria Hill, Stellan Skarsgård as Erik Selvig and Samuel L. Jackson as Nick Fury.

"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, Pietro Maximoff, played by Aaron Taylor-Johnson, and Wanda Maximoff, played by Elizabeth Olsen and meet an old friend in a new form when Paul Bettany becomes Vision."
