(Spoiler)This is definitely a nostalgic movie, a nice tribute to Harold Ramis. The movie itself is not much an original story but more of a repeat of the second movie. Yeah you can argue that but reality is it was not original enough. Either way I watched it expecting more, but got the remnants of that last version. If you're a fan of the original it will be a nice addition, but if you're expecting something new/original there's plenty else you can watch.
