Dead alien body in a warehouse is ok, living aliens that make angry faces at Spalko is George going overboard and no one having the balls to tell him to shut his whore mouth and sit in the corner.
Biggest things I'd like to change are :
End the prologue w/ the Rocketsled, transition back to Marshall w/o nuke or interrogation
Fix/shorten the swordfight w/ Mutt and Spalko so it's more brief and believable and w/o any nutshots or straddling the 2 cars
No monkies or swinging, Mutt gets hung up we don't see him again until he just swings out of nowhere into Spalko's car
1 waterfall instead of 3 and not as long a drop
add fight between russians and Ugha
Fix Mac's death to look more believable
No living aliens, no wedding, just change all the dialogue at the end between Marion/Indy/Mutt "Why didn't you stick around dad?" "Somewhere Grandpa is laughing" "Knowlege was their treasure" all of those lines are attrocious.
