No, I think it's a thoroughly mediocre RPG. That said, this is entirely not the fault of the game or its designers. D&D is and always has been a gamist-simulationist RPG (and sadly the already subdued simulationist part is shrinking) and therefore it is, by its very nature, not for me. As far as I can observe, 5E has been pretty decent gamist design, if only a tad bit flavorless but that's a minor complaint. D&D 3.x wasn't very good, even for it's time. It was an updated version of D&D that reflected changes in general game design that AD&D had missed out on. It was much clearer game design than AD&D, however - but it had several other flaws.
