In the Elder Scroll tales, Oblivion got damn close to perfection, but, it to needed tweeking too.
Just lost credibility there. If you are talking about hyping the game and the game deliviering, you are OH so wrong there my friend. No disrespect to you, but I disagree with you there. Oblivion did not deliver on what was hyped. Todd did hype up Oblivon as Morrowind 2.0. As we all lernt, Oblivon is it's own game. I love Oblivon, just as I love Morrowind, Daggerfall and Arena. Disapointed with Battlespire, in fact never played it much (just wasn't interested in it) and never got the chance to play Redguard. Because of Todd's hype of Oblivon, I stayed pretty much away from his hype on Skyrim. From what I have been reading, it was a wise choice for me to do that, otherwise, it would be the same for you, disapointed in Skyrim at first.
From reading your post, you were expecting Oblivion 2.0. I guess now you know how Morrowind fans felt. Also, what is the good things about the game? I don't see you listing any in your post. Guess we are alike we ramble alot missing out on what we want to say.

I say yes it's a TES game. In fact each TES game is different from it's predeccessor. When TES VI comes out, it will be different from Skyrim. If we are going to say what is not a TES game, I would say it was Oblivion on first release. I hated it so much that it wasn't Morrowind 2.0 (mainly because that is what Todd hyped it up to be, nice to see this is the one mistake he didn't do with Skyrim saying it would be Oblvion 2.0) but after a month away from not playing Oblivion I have lernt to love the game for what it is. It is it's own TES game. Same thing for Skyrim. It's not Oblivion 2.0, it is it's own TES game. Do what I did, do not think of Oblivions game play or in my case Morrowind or Daggerfalls game play, but play it as it's own game.
As you said, if it didn't have the TES name in it, it would be a great game. I find Skyrim an awsome game just because of the experiance I have lernt from Oblivion when it was hyped and released.
Trust me, I know how you feel. Once you get passed what was hyped, what was promised and not comparing it to it's previous TES game(s) you may just love Skyrim for just being Skyrim.

Again I fully understand where you are coming from.
