I believe singer can, look at the x-men films. Superman returns had no super villains at all. so I dont think there was so much action lex could cause. It had more action then the original superman and on an epic scale. Im sure when he gets the chance at handling such baddies as metalo, doomsday, etc. he will have those big action sequences we all want.
I don't know about that. STM had:
1. Krypton Exploding.
2. Baby ship crash landing on earth.
3. a helicopter crash and him saving Lois and it
4. Him standing on the side of a building and then chasing after and catching a cat theif.
5. Catching bank burglers and then picking up their boat and leaving it in the middle of a street in Metropolis.
6. Lightning taking out an engine and part of a wing and him catching it and flying it back to safety. (which was redone pretty much in SR, just expanded)
7. him drilling though the ground and walking through a hallway full of bullets, flame throwers, and a freezing room.
8. Him chasing and catching one nuclear missle and sending it off to space.
9. Another one crashing into the San Andreas Fault and causing major destruction.
10. Him flying undeground and pushing the fault line back up to it's original position.
11. Saving a bus from falling off a serverly injured Golden gate bridge
12. Him stopping a train derailment.
13. Him saving a power plant
14. Him catching Jimmy from falling off of a breaking Hoover damn.
15. Him outrunning and then using a rockslide makeshift damn to stop a town from being whiped out from flood waters from said damn.
16. Lois being killed and him pulling her car out of a crevace.
17. Him turning back time to save lois.
18 delivering Lex to prison.
SR
1. A crashing ship back to earth (already done in STM so nothing new)
2. A plane in trouble (already done in SRM so nothing new, just expanded upon with a space shuttle)
3. Him stopping a bank robbery with a gatlin gun (done in STM twice with a bank robbery and a hall filled with machine guns)
4. Him catching a person on TV (done in STM)
5. Him blowing out a house fire on TV (short scene)
6. Him stopping a guy falling off of a crane (short scene)
7. catching a hotel sign (short scene)
8. using laser vision to stop glass (short scene)
9. stopping a gas fire (short scene)
10. pulling up a boat from sinking (not so impressive as it is just the actor standing on a set being lifted out of the water)
11. picking up a plane and heading it in the rigt direction
12. picking up New krypton
Lex Luthor isnt even caught by him, and runs out of gas on a beach. And except for having more action in STM, all of the scenes in it with exception of the plane rescue are much more expanded in STM than in SR, which a lot of them are relegated to a short 10 to 20 second shot on a TV screen.
