In Star Wars: The Force Unleashed. Spoilers, obviously.

• Hmmm... Let's start with surviving a lightsaber through the chest, being smashed into like three walls, then thrown out a window into the FUCKING VACUUM OF SPACE. And surviving. Needing nothing but an arm brace.
• Being able to bring down a gorram (yes I said gorram. Watch Firefly dammit) Star Destroyer, but not pick up an AT-ST, or stop the Rogue Shadow (Darkside ending)
• EVERYBODY FORGETTING ABOUT THE FOUNDER OF THE REBEL ALLIANCE BEFORE A NEW HOPE
• Luke never ever running into General Kota, despite the fact that they're two of the few remaining Jedi, and both key Alliance commanders
• The Rebel Founders completely IGNORING a giant fucking space station with a laser big enough to destroy planets for three years before deciding to do anything about it.
• Bail Organa not GTFOing Alderraan when he saw said giant fucking space station jump in-system in A New Hope
• PROXY using the Force when you fight him O_O
• Oh, also, Vader totally uses Force Lightning in the boss fight against him (Well, you can lightning lock with him), which would totally be impossible, seeing as Vader has mechanical hands and all.
