Honestly, the only thing Top Gun 2 doesn't have to do is bring back a dead cast member back to life via CGI. And all the principal actors are alive, so we're good.
Afterlife is absolutely atrocious, but I think the Harold Ramis moment is one of those rare sequences in cinema that's so wretchedly godawful and despicable that it deserves any and all backlash given towards the entire movie solely on that moment.
