Honestly I don't understand all the hatred toward Shia LeBouff, I thought he did a pretty credible job considering what they gave him to work with. It was Spielberg who made him do that ridiculous sword fight on the vehicles and swing through the trees like a damned ape. I liked him other than that.
And why hasn't anyone yet suggested some adventures with Wu Han, Indy's friend who pulled the gun on Lao Che in the club Obi-Wan? "I've followed you on many adventures...but into the great unknown mystery...I go first, Indy." So lets see these adventures, he could be a cool character if developed further.
Anyone? Bueuller? Anyone?
I wanna see the "interquels" where Indy worked for the OSS during WWII. More Nazi-punching, please!
In all seriousness, though...I'm good with just the three. That's all I need. I treat YIJC as its own, entertaining thing, although it's not REALLY Indy to me. I enjoy the video games and comic books, but that's because I can always turn a blind eye towards anything I don't like.
With the films, once I see it, it's stuck in my head and I'll never get rid of it.

For me, once I see a film that's "officially" within the continuity, it affects my view of the other films. I know that's not true for a lot of folks -- a crappy entry into the film series isn't really a problem for them and they can still enjoy the good stuff. But for me, especially in an ongoing narrative, it really hurts my enjoyment of the other material.
The only case that comes to mind where this doesn't happen is Bond movies. I happily ignore large swaths of the Bond franchise, and simply enjoy the films in the series that I enjoy. But that's also because you have 20+ films, 6 different Bonds, and several distinct "eras" to the franchise.
