OTHER OBSERVATIONS
Both LG15 and The Sopranos leave a bunch of storylines unresolved.
Both LG15 and The Sopranos have a highly dedicated fan base.
Both involve lots of secrets, breaking and entering, and following people.
Both make "drops" in bodies of water.
The Order dresses in Black, so do Italians.

Hmmmmm, what else?
