The Stormtrooper Hypothesis surmises that the quality of each of the six Star Wars films can be measured by the level of awesomeness of the stormtroopers featured in the film. The Prequel films are included in this hypothesis because, although the do not contain any actual stormtroopers, two of the films contain a stormtrooper-like substance, the clone trooper.
Star Wars (or, A New Hope)Edit
Stormtroopers are present in this film. Stormtroopers totally ransack Princess Leia's ship like a horde of vikings. It is here where we learn that, despite onscreen evidence to the contrary, they are really good shots. ("Only Imperial stormtroopers are so precise.") Even though they do exhibit below-average marksmanship for the rest of the movie, they come out swinging, blasting away at everything in sight.
Bonus points for: Sandtroopers.
The Empire Strikes BackEdit
They pwn Echo Base. Hard. Quite possibly the most awesome stormtrooper uniform ever, the Snowtrooper. Rode to work in giant armored elephants. Blew C-3PO the fuck up. Looked awesome in the Carbon Freezing Chamber. Blasted the hell out of Cloud City. That's how they roll, bitch.
Bonus points for: ZOMG! Snowtroopers!
Return of the JediEdit
Two words...Fucking teddy bears. The less said about this, the better.
Bonus points for: The second coolest stormtrooper uniform...the Biker Scout.
The Phantom MenaceEdit
There are no stormtroopers in this movie.
Attack of the ClonesEdit
The first appearance of clone troopers. They did stormtrooper-y things. Looked slightly anorexic.
Bonus points for: The white armor, I guess.
Revenge of the SithEdit
Even more stormtrooper-like than the not-quite-stormtroopers of AotC. Kicked the crap out of a bunch of smarmy Jedi Knights.
Bonus points for: multiple new unit markings. Snazzy!
Using The Stormtrooper Hypothesis, the six Star Wars films are ranked thus:
1. The Empire Strikes Back
2. Star Wars (ANH)
3. Return of the Jedi
4. Revenge of the Sith
5. Attack of the Clones
6. The Phantom Menace
