I despise orders like this. It acts like the plot is the only factor to understand the show. Those other episodes weren't just filler. They were character development where they learned lessons.If you do want to watch more of TCW, I'd actually advise to follow this guide instead:
Just make sure you include all of the "Honorable Mentions" in your watch along with what is actually highlighted.
The reason being... this series does have its fair share of actual bad/stinker episodes and the vast majority of the episodes not highlighted as "required" or "honorable mention" on this list fall in that category.
If you follow the chronological list, especially, you end up seeing quite a lot of stink (Especially that pilot movie) before you get to anything decent.
If someone wants to watch TCW, do it right and watch it from beginning to end. It's worth it.
