With executive producer Dan Aykroyd at the helm, many people were worried that this reboot (complete with cameos from original Ghostbusters) would be horrible.
Oh how wrong they were.
The new Ghostbusters film isn't just amazing, it is arguably better than the first film in the franchise. This film is the "Batman Begins" / "Iron Man" of Ghostbusters films. It shows how they became the Ghostbusters.
Dan Aykroyd co-created the Ghostbusters franchise with Harold Ramis (Egon Spengler in the first two films) and for many years Dan and Harold sat on the franchise rights, wanting to make a 3rd film but never getting around to it.
Harold Ramis died in February 2014, his goal of a 3rd Ghostbusters film left unfulfilled. He stated back in 2009 he was hoping to get the film out in 2011, but when a serious illness knocked him off his feet in 2010 and robbed him of his mobility. He had to relearn how to walk again, but the illness relapsed and he again lost his ability to walk. He later died of complications.
A third Ghostbusters film was basically Harold Ramis' dying wish.
And so Dan Aykroyd made it happen, but with the realization that the original cast was too old to be pulling off the action stunts. Instead they recast everything, added cameos of the original cast members, placed a statue bust of Harold Ramis inside the old firehall, and did an amazing job writing a new film which depicts The Rise of the Ghostbusters. In all their humour and glory.
Naysayers of this film have lots to say about it, but sadly that is all they are: Naysayers. They haven't even SEEN the film. They don't know how amazing it is. If they had seen it they would know this is an incredible movie, that they did everything right in it, and that it should be winning awards for Comedy of the Year.
Also when you go see this film, definitely see it in IMAX 3D. It is totally worth it.
