Delilah & Julius

I would personally describe the romantic tension between Julius and Delilah to that between Mulder and Scully in the X-files, where both are attracted to each other, but neither dares let the other know. Mr and Mrs Smith are actually married, so I can't imagine that the tension would be quite the same, although I have not seen that movie. The action is probably more the Mr and Mrs Smith style however, as in the "Mission Impossible" style, whereas the X-files was not so much action as intellectual (and paranormal). I watch this with my 12 year old son sometimes and I agree, it is kind of cute. It is one of the better animated series for kids out there.
