Just like the first time I watched S1 of Beast Wars, I only had to watch LoK S1 the first time and I have pretty much the whole story in my head as a result. This is thanks to the fact that S1 doesn't delineate much from its core plot. No side-stories means less to confuse the issue. Beast Wars had quite a few episodes that didn't add to the timeline, but not so much that I couldn't keep track of the core story. In fact, I can pretty much remember the entire story for S2&3. I wonder if S2 of LoK will play likewise.
