Some that didn't suck:

Superman II (the best of the original superman films)
Kill Bill
Lord of the Rings
Hobbit
Harry Potter and the Deathly Hollows

The porn version of Avatar went into production within days of the release of Avatar, and was a vastly superior film, particularly in terms of script and story.
