Anyone who says Skyrim is a bad game is flat-out wrong.
To the extent that this can be true I am willing to agree. I don't think that anyone is arguing that Skyrim is bad in a way similar to, say, DAII, and it certainly deserves praise for being an ambitious open-world RPG in an industry increasingly dominated by cutscenes and quicktime events.
Don't get me wrong, I'm not saying that one can't dislike Skyrim for one reason or another but as a game it succeeds on so many levels.
On the other hand, while I'm willing to give Skyrim points for trying, I wouldn't necessarily classify what it does as "success".
Comparing it to previous Elder Scrolls games invokes nostalgia to smooth over all the jagged edges of the design we didn't like leaving only the shiny finish of the things that we did.
This is something I would vehemently disagree with. The cry of "nostalgia" is a byproduct of the industry's focus on only hyping the latest products, and damages the credibility of games in comparison to other artistic mediums. If anyone tried to brand a critic of The Godfather Part III, Aliens 3, or the majority of horror sequels as guilty of "nostalgia" they'd be laughed out of the room. Looking at Skyrim in comparison to previous TES titles, the writing is weaker, the setting is poorly developed, and character customization and player abilities have been severely reduced.
I personally found Skyrim very enjoyable and far from an 'interactive movie'. The atmosphere was so thick you could cut it with a knife and there was plenty to do and see. Skyrim is a world that I will keep coming back to just so I can enjoy the little things like stalking deer through the many forests or climbing the various peaks to pick exotic alchemy ingredients.
I don't know what game you were playing, but the "atmosphere" of Skyrim is the naked Nord joke character from Morrowind copy-pasted a couple hundred times. They really didn't put any effort into depth or nuance for the Nord culture.
Bethesda put a remarkable amount of effort into the newest Elder Scrolls game and it shows. It is far from a hack and slash job hence why it's enjoyed substantial critical and popular approval. Skyrim gave me hope again that during these dark days in PC gamings descent into casual gaming, pay-to-win and Modern Man-shooter XVIII [now with thrice the level of brown but with one third of the new content you used to expect] that there is still hope because there are still some developers out there that are focused on making quality games with remarkable depth who may not be perfect but are at least trying to make it work.
The game was heavily consolized, as demonstrated by the terrible UI, cut features, delayed CS release, and Xbox content lockout. I'm willing to concede that Todd Howard is likely one of the few AAA devs who actually cares about his games, but I think there's good reason to question his competence. If the amount of features gained is compared to the features lost in Oblivion and Skyrim, you'd find it a quite unacceptable ratio.
