Pointless endings using Harry Potter as an example

[Rocket Edge]

Harry Potter laying a Stone Cold Stunner on Voldemort at the end.

[Cookie]

Voldemort informs the muggles of Hogwarts. Muggles nuke Hogwarts. Harry was there. Dies. Fin.

[Hazzard]

Voldemort agrees to a condition with Harry, to exchange Hermoine for his survival. Done. Deal. Volde sexually assaults her.

[Værn]

Voldemort and Harry are staring down for their final showdown... Harry reaches into his cloak to grab his wand and shoots at Voldemort before he has a chance to make a move.
The spell hits, and a cloud of smoke appears. As it clears, Harry sees only a log where Voldemort once stood. Temporarily stunned with surprise, three shurikens hit Harry in the back. Harry screams, reaches back and pulls out the shurikens... then he suddenly becomes extremely angry and sprouts nine fiery tails.
Harry focuses his power into his palm to form a spinning ball of pure energy and charges Voldemort. Voldemort focuses all of his energy into his hand until it begins to glow a bright blue color and emitting a high-pitched chirping sound and charges Harry.
(I don't think a more blatant Naruto rip-off is possible by this point.)
Harry is faster and lands his attack on Voldemort, killing him while Voldemort's own attack misses.
As Harry prepares to celebrate his victory over evil, Snape appears behind him with a gun and shoots him.

Does Harry simply walk into Mordor?

You cannot simply walk into Mordor.

Harry and Voldemort are in a fierce battle. Harry is about to deliver the finishing blow, when...

Harry: AVADA KEDAVERA (orwhatever)
Ron comes flying out of the bushes and jumps in front of Voldy
Ron: NO, MY LOVE!!!
(The spell goes through Ron and into Voldy killing them both)
Harry: O_O
Hermione runs out
Hermione: D-did you just...?
Harry: No! I-it wasn't like that!
Hermione: You bastard, you killed Ron!
Harry: Ssshhh!!!
Hermione: I'LL KILL YOU!!
Harry: AVADA KEDAVRA!
Hermione: x.x
Death Eater comes from nowhere
Harry: Where do you all keep coming from?
Death Eater: Want a cookie?
Harry: Sure!
Harry takes the cookie and while chocking to death, trips over a rock and lands on his wand, piercing his heart. Then he wakes up.

Harry: OH GAWD What an awful dream!!!
Sorceress Adel: Oh poor baby...was it that mean old snake man again?

[Del Murder]

Harry was in a mental institution the whole time, and this was all a fantasy world.

[Fonzie]

Voldemont: I had reeses for breakfest.

Harry: Candy for breakfest?!

Voldemont: No, it's reeses puff cereal!
