The ending made me ragequit the game, no joke.
I dunno why they thought repeating a battle setup you've already completed, this time providing you with three Chuck Norris allies/human shields, would provide for a challenge.
I dunno why they thought screaming at a cloud for half an hour would help build tension.
I dunno why it didn't occur to them that, if I'm meeting famous Gods that have been mentioned in Elder Scrolls titles, I'll probably be frustrated if my dialog with those Gods is limited to "hi" and "bye" without giving me any option to ask questions.
I dunno why they thought dragons flying in circles would send the message of "yeah this is the ending."
I dunno why they thought no one would mind if nobody in the world noticed you did jack.
After realizing that that truly WAS the ending (took a minute for it to sink in and for me to prove to myself there was nothing left), yeah I was kinda pissed. That was beyond bad.
Well you don't know a lot of things i dare to say...

Perhaps Skyrim "end" isn't an end at all -
voluntarily - and it is even understandable in an open game world like this where you can ignore totally even the main quest if you want.
Really,what are you expecting ? fireworks ? every damn pc "prostate" in front of you because you've smashed a Dragon in Sovengarde with the aid of three "obsessed" heroes that could have easily beaten the "guy" themselves?
I'm pissed of too by the ending,but some of you take too seriously this aspect perhaps,forgetting even that we'll have some Dlc that (hopefully) could bring more depth -and more answers - in this regard.
