If I were Eru...Boromir would not have died. Aragorn, Boromir, Faramir (and perhaps Denethor) would have had major conflict at Gondor over Aragorn's claim to the throne. I would have loved to read about Aragorn and Boromir's rivalry, and Faramir's side. Ooh, what about the four hunters? What if Eomer had recognized Boromir, and things would have gone differently at Rohan? It boggles the mind.

In the book universe, that's about the only thing I would have changed.

Now, movie. Bwahahaha.

Boromir would not have died. Legolas just dragged the storyline out anyway, so their places would have been switched.

Boromir would be welcomed back to Gondor with much fanfare, and a huge Disco rave.

Sam would invent break dancing, and so amuse Frodo.

Frodo would be LESS and LESS coherent as he got closer to Mt. Doom.

Denethor would lose his flammable cloak, and be dressed in a bright orange, fire-retardant suit.
