Haha, very ironic. I've been talking with some of my friends about the fact that a large majority of anime title's have at least one beach/hot spring episode that rarely has anything to do with the actual plot. Reading this topic I realized all it was was fanservice. But I don't think we can just flatly go ahead and say there is or isn't too much, it all really depends on the setting of the anime and how well its integrated into the series as a whole. The whole Lelouch thing was stupid, but not necessarily out of place in terms of the setting, but in regard to the plot it had no real meaningful value.
