IGN: Constantine, risking overexertion, gave us three-stories-in-one for its big season finale, "Waiting for the Man." With a big twist at the end involving Manny to boot! And it's exactly this sort of "clutter" that works best for the show.
When the series meshes things from the comic series together, it not only usually fills up the episode entirely (leaving little room for drag and filler), but it also creates sort of a Constantine mix tape. Which, when we're talking comic book TV shows, is almost the best case scenario. Pieces from the comics refigured in news ways and made to fit together with new themes.
