I think Fam is the cutest thing ever created for use in anime, so I have a hard time deciding which is my favorite, Ruin Explorers or Slayers. It is very close but I have to decide that Slayers is better because it is longer and a lot more interesting because all the characters are important to the series. You could cut out half of the characters in Ruin Explorers and still have about the same thing. If it weren't for Fam the whole thing wouldn't be worth watching. No offense to all you numbskulls who like it.
Nobody is perfect.
I just recently got into anime, and Ruin Explorers was my second buy. I saw not a single flaw in the lighting and colors. Lyle's flashbacks are particularly good in this aspect. The music on the other hand, I really loved. I'm not a music fan, but the two songs with lyrics are something I'd like to have on a cd.
