All episodic sci-fi shows can have all plot holes explained away if one considers each episode taking place in a unique time-line.

What about shows that are so bad that they have plot holes within an episode?

Unless the plot hole is within the episode?

Then each scene will be its own timeline.

I camt think of a good example, but im sure with bad enough writing/shooting there could be a plothole within a scene as well. Subdividing further would get very meta :)

What about mid season 2 part episodes?

I think Stargate did this at the end of the 8th season. Travel back in time to get an artefact, accidentally case a time shift, then spend the next episode fixing the timeline.
