Some people don't like non-linear open ended games, they prefer games that don't let them have any choice and always tell them exactly what to do.
Skyrim is a very big game, It's easy to see why it might overwhelm some people who aren't used to playing games like this.
I like Skyrim and find it having its strengths and weaknesses as with all the other core TES games (Arena, Daggerfall, Morrowind, Oblivion), which I have played, but I'm pretty sure the complaints are about Skyrim's lack of choice. If you're insinuating Skyrim needs to be made even more accessible... no, it really doesn't. I think the problems are complaints about just how "accessible" it really is rather than how inaccessible it is, contrary to what you're claiming. Skyrim doesn't have much choice. Factions mean nothing, the very scarce and sporadic quest choices, when they do appear, rarely mean much, there is no reputation system, there are no hard choices to make, there are no branching paths and, well, that's that. Skyrim offers "choice" in the manner of "which house do you want to buy first, which type of equipment/fighting style are you going to utilize, and in which direction do you want to specifically run at this moment", but little else. Skyrim is not a very choice-filled or overwhelming game by any means, unless someone is just that indecisive when it comes to the order of map exploration, and none of the games of this series have ever really had much choice and consequence, but it has deteriorated. Reputation systems, at least... there isn't even a reputation system in Skyrim. No... the continually worsening lack of choice in any TES game post-Daggerfall is not a process that needs continuing in order to appease certain people. The opposite needs to occur, I would think.
Though, that was a tangent off of the OP's topic. I think Skyrim is great game, but this series could use some more choice, not the continually decreasing lesser amounts.
