It is the word garbage that I would always take offence to. That is more than opinion, it's a judgment of worth.
In my critique of Mangog under Jurgens I don't say "and so Jurgens was a terrible writer". He is categorically one of the better modern writers.
I think Mangog was handled very well by Aaron, respectful of continuity (more than I would have been) and thematically appropriate. As I cross-posted above once I found the references.
