'Indiana Jones and the Kingdom of the Crystal Skull' received its world premiere last night at Cannes where it received a mixed reaction from critics.
While some praised the long-awaited movie, others were underwhelmed and the overall impression was of a film that wasn't truly bad, but failed to be brilliant.

Harrison Ford, who returns to the role of Dr Jones 19-years on from the last movie, insisted he was not concerned about the critical reaction to his latest adventure, saying the only people who mattered were the fans.
Excitement surrounding the film reached fever-pitch as the cast and crew attended the screening, with thousands of fedora-wearing fans lining the streets to cheer on the stars.
Those involved in the film, including Cate Blanchett, Shia LaBeouf, Ray Winstone, Karen Allen, George Lucas and John Hurt, received a standing ovation as they entered the cinema.
The massive celebrity guest list included Goldie Hawn, Cannes jury member Natalie Portman, Dennis Hopper, Linda Evangelista, Christian Slater, Tamara Mellon and Salma Hayek.
Speaking at a press conference, 65-year-old Ford said he was not afraid of what critics thought. He said: "I expect to have the whip turned on me. It is not unusual for something that is popular to be disdained by some people and I fully expect it. I'm not really worried about it. I work for the people who pay to get in - they are my customers. My focus is on providing the best experience I can for those people."
The fourth instalment in Spielberg's blockbusting adventure series begins in 1957 during the Cold War. Indy meets rebellious young Mutt (LaBeouf), who carries a grudge and a proposition for the archaeologist - if he will help on a personal mission, he could make one of the most spectacular finds in history - the Crystal Skull of Akator.
But Soviet agents are also hot on the trail of the crystal skull, including Irina Spalko (Cate Blanchett), whose elite military unit is scouring the globe.
Asked how Spielberg had changed over the last 20 years, Ford said: "As brilliant a director as he was 20 years ago, he's even better now, and I don't know how that's possible."
Spielberg said there would be more Indiana Joneses "only if you want more of them... We will have our ear to the ground to hear what happens and that will decide where we go from here."
He said it was 26 years since ET debuted at Cannes adding: "I'm very honoured to be back here again."
He continued to say that Ford started the ball rolling, saying maybe he was ready to put the fedora back on. "I had to be convinced the most, out of everybody."
Spielberg continued: "We thought that because this film was well-known the fair thing to do and the fun thing to do would be to view it when the entire world comes together at this festival."
'Indiana Jones And The Kingdom Of The Crystal Skull' is released in Ireland this Thursday, 22 May.
