After 10 minutes, I didn't care anymore. I guess I'm getting old - the special effects were good and Harrison Ford was surprisingly spry! I guess I've just had enough, over the years.
I did like the reunion feel with some old characters returning or at least, prominently mentioned. The humour wasn't quite as fresh and the plot was especially outrageous but this was an Indy flick.
Don't go if you're tired at all - the special effects will wear you out.
