I think boring and lacked action are linked for you. If action means Supes hitting a bad guy the strongest that he can in order to instill order in the universe through his fists, then yes SR was boring, (hopefully) boring.
There is the plane scene, the boat rescue, the whole island scene, and the save of Metropolis. Furthermore, action doesn't only mean big fight, but scene with something happenning. This is the case with Lex Luthor, he is always in movement, always learning something. And the scenes between Lois and Superman, something is happening.
Stalker if you want but I think all the scenes I mentionned before (plane, boat, island) are heroic.
I found Lois really pretty. Not that it is what matter the most for me, and even if I keep loving Teri Hatcher as L.Lane. K.Bosworth expressed enough sensitivity and concern toward Superman, it's good enough for me.
