Every now and again they'd push the boundaries and give us a good moral drama without throwing the reset switch, sadly though this often was a very rare event.
I found a lot that in the episodes where they're supposed to be grappling with their issues and facing a truly difficult decision the consequences are never really explored or the whole thing is just rushed through, I see Tuvix as an example of this. Is a shame really as DS9 and Enterprise showed that the producers were willing to take the risks to create those good stories with a hard dilemma at their core.
