This is easily one of the most popular films ever made. And thankfully, it's also actually an excellent piece of work in its own right.
What we get here is the story of some "paranormal investigators" who, after getting kicked out of Columbia University and having their grant revoked, strike out on their own using homemade equipment to capture ghosts, ghouls, and all manner of otherworldly spectres that start plaguing NYC.
First off, this is just an amazingly clever, creative, and fun premise. The ghost effects are charming, sometimes rather creepy, and altogether a sign of imagination at work. More importantly, this film is quite witty, funny, quotable, and memorable. The characters are what really make this work. As the Ghostbusters, we get Harold Ramis, Bill murray, and Dan Aykroyd as the original trio, and Ernie Hudson as a new recruit, taken on to help curb the increasing level of paranormal threats. All of these guys are in top form here, and they really have excellent chemistry. I like them all, and for different reasons, but as a kid, Winston (Ernie Hudson) was my favorite. But then again, you can't go wrong with Ray's (Aykroyd) bubbly enthusiasm, Peter's (Murray) dry sarcasm, or Egon's(Ramis) nerdy technobabble.
As their first client and Peter's would-be girlfriend Dana, Sigourney Weaver is incredibly gorgeous, and quite solid. Rick Moranis is a delight as Dana's doofy accountant neighbor Louis, and Annie Potts is a scream as Ghostbusters secretary Janine. And, while the film could have worked just fine with ghostly baddies, we also get William Atherton as an antagonistic EPA agent.
Trying to pick a favorite line or moment is just way too hard for me. The film is loaded with lots of little and big moments that are just comic and cinematic gold. The script by Ramis and Aykroyd is razor sharp and creative. It wasn't until I was an adult that I was able to catch all the jokes that flew over my head as a kid. Even then, I still notice new things each time I watch it. Ivan Reitman's direction is light, yet assured, finding a good balance between plot and character moments. The music by Elmer Bernstein is diverse, but well blended, fun, and like the movie itself, quite memorable.
This has been one of my all time favorites for basically most of my life. Even if it wasn't, I'd still probably be a big fan just because of how unique and enjoyable this all is. Bottom line: it's not only a must see, but it's a one that bears endless repeat viewings.
