I don't sincerely know what to think. I don't really see a lot of possibilities for a fifth film to be actually made... Harrison is getting too old, we must face it.
Sadly, the right occasion for an explosive return of the Man With The Hat was the last one... but they preferred to miss the shot by far with "Kingdom"...
And, as my personal note... I don't know if
I would like to see an "Indiana Jones 5". Number four was so disappointing that I really don't know what to expect. I feel like I don't trust Lucas' and Spielberg's ideas any more.
A part of me would really like to see a prequel which could try to
correct all the mistakes made in "Kingdom of the Crystal Skull" and worthily take its place as the fourth and
conclusive chapter of the best adventure movie saga ever, but... on the other hand, I perfectly know that if the fifth film was ever made, it would be a damned sequel with Marion, Mutt, Indy as a family man (!!) and all the freaking rest. It would almost certainly be a mess... perhaps even worse than "Kingdom"... I don't know... I don't really know...
