Is any comic necessary?
I think with Thanos playing a starring role in the latest Marvel crossover, and also the movies, it makes sense that they'd want to be able to point readers to an easily accessible, modern origin, that doesn't have too much baggage in it.
When the previous version of the character is more complex and better in just about every way, then yes.
This is a dumbed down version of Thanos.
