What I liked most about Raiders of the Lost Ark was that rough-around-the-edges, gritty type of sensibility that has gradually dissolved throughout the series.
.... Plus, I think a big factor in separation from the rugged quality of Raiders to the quality of Crystal Skull was that everything seemed too polished and neat. The cinematography was way too polished and clean for an Indiana Jones movie. Even the locations and sets and special effects had this very pristine quality that felt totally out-of-place
A good point. Let's compare some college shots from
Raiders...
to some college shots from
Skull:
Here's Indy's house in
Crusade:
Skull:
A creepy place from
Raiders:

I agree with
JacksonArcher. Storybook/painterly color can be used to great effect in outright fantasy (
LotR,
Harry Potter 3 and 4), contemporary comic book fantasies (
Iron Man,

The Good Shepherd covers periods close to
Skull's, and with a similarly dreamy look). But the downside to the perfect lighting, super-high contrasts and general prettiness is a creeping sense of unreality. May not be a big deal for Frodo, Tony Stark or even
Casino Royale's Bond, but when Indy's defining characteristic is gritty, sweaty authenticity, the visuals and character are badly at odds.

The Mummy Returns:

Raiders than
Skull does.
