Only that you are not really interacting with the environment at all. You are just placing traps everywhere and no one reacts to it.
So much this. It fascinates me how putting explosive barrels next to non-hostile victims and then blowing them up is somehow considered 'environmental intractability'.
Then again, we all know that explosive barrels & crates are a staple of good & original game/map/level design. The more the merrier...
