1. Really? EVERYONEs been brainwashed? That's he ingenius plot? Despite that half the town should probably know Lauloch and/or Nunallay (bing in the studen council and having friends, etc..), the Emperor somehow brainwashed everyone AND got rid of all physical evidence of Nunnalay (such as albums and photos in others peoples houses). Just weak.
Not to mention it compleely destroyes some characer developmen and plot poins (like Shirely finding out again that Luloch is Zero)
2. Despite Leuloch being under constan survailance by cammeras and observers (and it being stated that he couldn't possibly use the Geass wihout them noicing) - he's constanly using it without them noticing. Even out in the open in a crowd (the pizza incident)! WORST. SURVAILANCE. EVER. Not to menion the weak-ass blackmail that everyone falls for (You'd think capturing Zero again would gain you a TON of points).
3. Battle Loli's. Frak them. Frak them a bajjilion times.
4. More bulls***...like the missile-launched flight units and replacement arm that happened o appear JUST as a mecha was falling. WTF???
5. Suzakus stupidity. The whole phonecall with Nunallay thing. Instead of gauging the inital reaction (turn around so I CAN'T see your face) he banks on Lauloch just talking normaly and breaking cover afer a minute of stunned silence (the friggin minute of stunned silence should have been enough of a clue)
