I love Indy films (and other Expanded Universe stuff as well), but I think that 70-something action-adventure hero is pushing the boundaries too far. Even, if Harrison Ford is the only man which can make this idea work.
But I give the credit of trust to Spielberg and Ford (and Lucas) and I hope, that the fifth installment will be great.
Only one think makes me a little angry - if the creators are so eager to make more Indy films, why haven't they done it in the 90s? We could have at least two trilogies by now.
One can dream...
Anyway, I have my worries for the fifth one, but I am first to buy the ticket.
