I'm not going to watch the second trailer because I want as much of the movie to be fresh for my eyeballs the first time I see it (not to mention I already know most of what the second trailer reveals) but I don't have a problem with Afterlife being forged in a mold of an 80's Spielberg adventure that might lean a little more serious and heartfelt than deadpan comedic force.
The original film is such a masterful confluence of comedic talent that you're not going to ever be able to replicate it's master class presence. You're just not. So I have no problem going a different direction and I actually really appreciate that they are going a different direction in Afterlife. It would be so, so easy to just roll out the tired idea of 'new team of young comedians are the next generation of GBs and get saved/trained by the original gang'. I'm glad we're not getting that for a multitude of reasons. Grandsons of an original team member, a single mother, family lineage, living up to a legacy; those are much more interesting topics to delve into in the framing of a GB movie. If Afterlife has heart and passion behind it, I think it'll resonate with a lot of people and given the talent on both sides of the camera, I think it'll be a great film.
That said, take my opinion with a gigantic grain of salt. Ghostbusters touched my soul when I was little and it's one of my favorite franchises in the entirety of cinematic history. It speaks to me on so many levels, so chances are I'm more than a little biased towards any GB property that is developed. I enjoyed Answer the Call but there was so much untapped potential there and it just wasn't handled with the care the brand deserves, IMO.
