Don’t listen to the trolls, this is a funny and very original reboot.  The story centers on Erin (Wiig) and Abby (McCarthy), two egghead scientists whose lives have taken different paths.  After Erin is coerced into helping Abby and her new partner Jillian (played oh so well by Kate McKinnon of SNL fame) catch some ghosts, the team is reborn.  After recruiting newcomer Patty (or did she recruit them?), the fearsome foursome battle city politics, and a skeptical public on their way to saving the city from a dark menace intent on unleashing all the evil spirits trapped in the realm between the dead and the living.  Inspiring comedic performances by Chris Hemsworth as Kevin, a pretty-faced, but completely inept receptionist and of course Kate McKinnon as the eccentric Dr. Jillian Hotzmann.  Stay through the initial credits for more fun.  The only downer was the special effects used to create the final ghost (unless the film-makers were purposely doing an homage to the original 1980’s special effects capability).  The original cast does manage to make it back onto the screen this time and each is used perfectly and in no way suggestive that they had any past involvement with Ghostbusting.  Even Harold Ramis (who died last year) is represented, along with Ernie Hudson, Dan Akyroyd, Bill Murray and even Annie Potts who portrayed their original receptionist.
