To even the casual moviegoer, "Iron Man 2" didn't make any freaking sense.

We are prepared to believe a genius can make an impenetrable suit in a cave with basic tools. But just because a superhero flick is based on a ridiculous premise doesn't mean the rest of the story has to be completely nonsensical.

So these are the biggest problems we caught. Notice anything we missed? Let us know in the comments.

12. How did Iron Man bring about "world peace"? And so quickly? He's just a guy in a suit with a couple of weapons. Can he stop a nuclear attack? No. And, if there is no more war then what does Stark Industries do?

11. How can Lt. Col. James "Rhodey" Rhodes just take a suit? Is there no password protection? No software to keep random people from flying off with it?

10. Why does Tony Stark have a version of Captain America's shield in his office?

9. After the attack in Monaco, Whiplash tells Tony that there's "blood in the water" and the world will come after him now that they know he's not invulnerable and then ... nothing happens. No one comes after Iron Man.

8. If S.H.I.E.L.D. agents are around all the time, why doesn't anyone of them help out when the army of Iron Man drones attacks the Stark Expo?

7. Why does the double blast of repulsor rays from Iron Man and War Machine defeat Whiplash when it didn't hurt them all that badly either time they did it nor did it even have enough power to blow up the room they were in Tony's house the first time?

6. Whiplash attacks Iron Man on international television, but is defeated and sent to jail. Soon after a bomb explodes in his prison cell. Why didn't any of the characters in the movie know about this when it happened? And, why did it take so long for them to find out that Whiplash didn't die in that explosion? Just because the other prisoner had on a similar jumpsuit? Are the police that dumb in Italy?

5. Why doesn't Tony Stark know that his father had a partner that co-developed the Iron Man technology? And that his father had him deported? So the arc reactor is embedded in his chest but he didn't bother to learn anything about the history of it.

4. Why doesn't Whiplash die or even get hurt when he's repeatedly rammed by a car?

3. Why does Pepper Potts as CEO of Stark Industries allow their chief rival Justin Hammer to take center stage at the Stark Expo to show off his weapons which are in direct competition of Stark's weapons?

2. Why does Tony's father hide a clue in the design of the Stark Expo instead of just telling Tony (or anyone else for that matter) about the element he has in mind?

1. Is there honestly no one more qualified to replace Tony Stark as CEO than his assistant, Pepper Potts? Does anyone else work for this billionaire outside of her and Happy Hogan?

One More for Good Measure:

Whiplash is originally somewhere in Russia, right? How did he transport the Whiplash battle suit from there to Monaco without any problems?
