What is it you're trying to include (or exclude) from the view, and what is the purpose of this rule?
Normally, a view for series would simply include all series, and that would be accomplished with a rule based on [Media Sub Type] or [Filename (path)] (e.g., starting with "D:\Video\Series"). Such a view might then include Categories like [Genre] and watched status (e.g. using the expression If(IsEqual([Last Played], never played), Not Watched, Watched)).
