Yep, that's what his posts clearly imply. He just doesn't see it.
Many others have also pointed out the same lack of energy in KOTCS as its main shortfall.
But surely this is inevitable for any movie with an older Indy, set in the 50s or 60s.
Put simply, in order to maintain the film series' typical level of action and energy in the face of an aging main character, there are only two possible alternatives.
A) Assign a more active role to other characters, like Mutt.
But by definition their action scenes cannot be longer and/or better than Indy's, or it's not an Indy movie anymore. Hence the overall lack of energy.
B) Relegate older Indy to a bookend-type role and show most of the action scenes in flashback, with a younger actor in the lead role.
That's it.
And that's why I for one have no desire to watch another Indy movie with Ford, unless he accepts said bookend role.
And yet, ironically, we get so many Raveners complaining about the lack of energy in Skulls, while at the same time clamoring for Ford to carry the whole Indy 5 on his own.
