There is no set definition of the word "classic" but I'm sure this film qualifies as such or will in the near future, since it was so unique and popular....and remains so today, over 20 years old later. It's just one of those films that you remember seeing when it came out at the theaters. I doubt if anyone has forgotten the catchy theme song, either.
Despite numerous viewings, I still find this very funny as I suspect many people do, because it entertains so well. I know the story is ludicrous and I don't believe for one second in ghosts so I ignore the "theology" and just laugh at Bill Murray, Dan Ackroyd, Harold Ramis, Rick Moranis, Annie Potts and Ernie Hudson.
Murray, as he tends to do, grabs the spotlight more than the rest and delivers more laughs than any of the cast but my favorite was Moranis as the nerdy "Louis Tully." I wish his role had been bigger. All the guys, however, plus Sigourney Weaver, the love interest of the always-horny Murray, are fun. I even liked the sequel because most of this cast was included.
