Its real easy:)

*Claps enthusiastically* I agree with every one of these, especially Back to the Future. Both sequels were complete and utter shit and should never have been made.

And I don't necessarily pretend the three Indiana Jones sequels don't exist ... they're just an entirely different thing from Raiders for me. Raiders is a perfect film ... and then Spielberg made three movies starring Harrison Ford that all happen to have Indiana Jones in the title. They're not completely awful (that includes KOTCS) ... they're just painfully average.

That's the last I'm going to say on the Indy sequels - I'm starting to feel like a broken record.
