Now that I have a real keyboard and am not sleep-deprived...
For those unaware, Ivan Reitman directed the original Ghostbusters. Jason is his son. Two of the original three Ghostbusters writers are still with us, Dan Akroyd and Rick Moranis (Harold Ramis, RIP), and Ivan Reitman has agreed to step in as a co-writer. Akroyd teased the possibility of another Ghostbusters back in November 2018 and is indicating he has direct involvement with this project. Also, industry insider-speak is pretty adamant that this is a true continuation of the original, right down to the timeline which will have moved forward in time just like the real world. Same world, same characters, just 35 years older.
Akroyd, Murrey, and Hudson are still spry enough to pull off a decent film, especially if they go all-in an use their age as a plot point. Ramis is gone but of all the characters, explaining Egon's absence has the most comedic potential while still paying respects and homage to Ramis's and the character's legacies. Maybe Egon's ghost shows up to help save the day?
Also, no Paul Feig or cast of shrill, pompous, spittle-spraying SJWs.
You have direct involvement of some of the original key players (admittedly one is by familial association, but still), they appear to be fully aware of fan expectations, they are trying to stay true to canon, and the teaser hits all the right notes without devolving into the "in your face!" mess that Paul Feig's abysmal first trailer did. I'm genuinely stoked. I hope they don't muck it up.
