I guess you may be right. It's easier (for me, at least, and seemingly most people) to criticize a product for its faults than it is to appreciate it for its successes.
I think that at the time Morrowind changed gaming in a way completely unforeseen by both the industry and its customers. And it was the gateway into the TES world for a lot of us, so the impact of that particular entry is undeniable.
But what we have to keep in mind is Morrowind had game breaking bugs, was repetitive and slow, had similar script issues (I just stole all your stuff and you want to buy it BACK?).
But over the years with the AMAZING expansions, mods, and community, it's STILL one of the greatest gaming experiences I've ever had. There's a reason people are still playing/modding it.
I truly believe this will happen for Skyrim as well. It's been less than a month, the creation kit isn't even out yet, DLC hasn't even been announced.
Skyrim will not be complete until these things happen. In a year, the experience will be incredible. Just give it time
