I am not at all disappointed or frustrated that we didn't get any other Indiana Jones films after "Last Crusade." They told us in 1989 that it was going to be the last film in the series. I was cool with it then and I was cool with it during the long gap before KOTCS came along.
When plans for Indy IV were announced, I was definitely skeptical. Having seen the recent output of Lucas and Spielberg, not to mention their respective meddling with their older films, I had little faith that they were capable of delivering a new Indiana Jones film which could stand shoulder-to-shoulder with the previous entries.
How right I was.
I would rather have no Indiana Jones product than crappy Indiana Jones product.
I am sorry that KOTCS was made.* I honestly wish it wasn't. I don't lament the decades where no Indy films saw the light of day, I lament the crappy film we got and the fact that it tarnished the legacy of what was one of the most beloved franchises in film history and, of course, a personal favorite of mine.
Though it is too late to do anything about that now, I really do wish everyone would walk away from the franchise rather than churning out another mediocre-to-lousy film.
Some things aren't meant to go on forever. Some things should end. Preferably while they're on top.
In 1989, Roger Ebert wrote, "...perhaps it is just as well that "Last Crusade" will indeed be Indy's last film. It would be too sad to see the series grow old and thin, like the James Bond movies.
We don't need five, six, seven, ten Indiana Jones films. Few franchises have that much life in them.
Yes, James Bond has been around for 20+ films, but as others have pointed out, how many of those are truly great? And that franchise has the luxury of re-inventing itself to at least try to keep it current. Not only do they re-cast the lead, but the series itself has wild, schizophrenic shifts in tone. "Moonraker" and 2006' "Casino Royale" have almost nothing in common.
Sure, there have been many screen incarnations of Batman, but again, their sensibilities are wildly divergent.
I don't want to see the same kind of reinvention applied to Indy. I can accept that the film series has run its course and that its glory days are far, far behind us.
I think we need to take a page from Henry Sr. and just "let it go."
*The single benefit, which is not insignificant to me, to the existence of KOTCS was the creation of the wonderful, if short-lived, Hasbro Indiana Jones figure line. Watching KOTCS was a very high price to pay for that, but I would be lying if I said I wasn't happy to get those figures. And the possibility of getting more figures is the only reason why I would have even the slightest interest in seeing an Indy V get made.
