For some reason the animation of this episode is horrible. It really detracts from a decent, although not great, script.
Hopefully nobody who has never seen the series, first comes across this particular episode. It looks and sounds like it comes from a different series entirely.
Its especially odd, because there are plenty of great episodes before and after this one was created, but this is the only one that looks as bad as this one does.
The voice work is great though, and there are a couple of important parts of the Superman mythos that are touched on, especially regarding his relationship with Jimmy Olson.
