Now that I've watched all three of the Citadel series--American, Italian, and Indian--I can compare them to each other, which I don't think is the original idea, but I'll do it anyway. But, that comes later.
Anyway, Citadel: Honey Bunny is a difficult six-parter to work your way through, even though it had some pretty good action sequences. But, the story is so lame and the actors are not engaging enough at bringing their characters to life or to make me want to care. The kid was the best actor to watch.
Now, to the comparison. Of the three installments, and much to my surprise, I'm enjoying the Italian, "Diana" the best. In fact, I've watched it several times. Though it lacked great action ("Honey Bunny" wins the Action prize), the "Diana" episodes draw you in, make you care about what happens to the characters--and Italy has never been more beautiful. Finally, the original "Citadel" comes in second because of it's clever plot twist, and the best acting cast of the three.
Final scores:
Diana = A-
Citadel = B
Honey Bunny = C+
