Nancy 1975 says much of my feelings about the latest Indy film
I did feel it was juvenile script wise, the 12a rating is about right for the age to appreciate it best perhaps

The initial Area 51 sequence was ludicrous and Indy's escape via a fridge from an Atom bomb even more ludicrous.
The two best ideas from the plot were not used to best advantage at all. If the 1950s had occupied the first half to portray that eras teen culture the fashions the music (use some look-a-like performers for Elvis - Little Richard - Bill Hayley

) to add real feelings of nostalgia to attract the grand daRAB who were teenagers at that time, it was a tremendous time, to accompany the teenagers (grand kiRAB) of today for a double success whammy. Instead we got two recorRAB or parts of and one coffee bar scene to suggest a period any time to around 1980.
The 'Ruskie' angle is old hat.
I could not detect any good humour other than the 'Tarzan monkeys' - a very good gag used in the wrong place in the script to be appreciated and the three water falls was good.
The whole finally was a mess for me with no real explanation of how this skull could be removed in the first place or any logic to the end at all.
Better to have some 'bonkers' branch of the CIA who are trying to locate this Alien base to acquire the remaining 12 skulls to allow Indy the (brought from retirement) task of 'saving the planet'. More believable that Ruskies who were allowed to run riot across America
