Y'know i've been thinking, one thing i could imagine as worthwhile would be a prequel miniseries of the original Ghostbusters going to college, built on references from the first half of the first film. Wouldn't even need paranormal activity in my book, just the boys bouncing their character shit off each other and life etc. (con is no Winston). Unfortunately that original chemistry is lost forever, can't think of any contemporary ensemble even remotely up to the task.
Ghostbusters is as dead as Harold Ramis.
That being said i'm probably still gonna watch this but yeah, 100% unexciting trailer. At least the cast seems somewhat solid... we'll see.
Edit: Also that CGI is fugly as hell. Invest in some practical effects / puppets ffs, the Mandalorian really shows how much it's worth it imo (besides being rather banal at least it's got the style down).
