***Possible Spoilers*** Roland opened the door at the top....

I must admit though, I'm confused as to why we would be told that there are 2 keystone worlds (Roland's and that of the world they met Sai Cullum) and within those worlds, time goes one way. No more chances to come back if a mistake is made. So how was Roland able to keep going backwards time after time?? Is he getting sent to different "whens" or "wheres" every time?

Also, the ending was very ironic.. Roland's ka-tet literally died and knowingly risked their lives saving the Beam at Thunderclap and how does the dark tower repay him? By giving him the chance to do it all over!

No. I think you are making a wrong assumption. Roland is getting another chance at redemption, not to replay the same series of events in the same way. Roland is back on the trail of the man in black but he will not meet the exact same people nor follow the same trails. There are an infinite number of similiar worlds and all of them bear their own evil. Only the Tower and Roland remain in the eye of the hurricane. Roland will walk his long road again but it won't be the same road. Everything that happened, happened. Those people and worlds go on. That beam was saved. In this next cycle I'm sure he will fight other battles, save other things, affect new people. His Ka-tet and those other worlds are not doomed to circle around again, only Roland is so damned.

I think this was the perfect ending, but if I had to choose one, I would have Arthur send Roland back because he neglected to grab Eld's horn, and he no longer had his guns, so he wasn't worthy of being there without a sigul.

could not be a better son.
could be a better finish.

I really enjoyed the ending. I mean it could have gone no other way. Ka is a wheel and it is constantly rolling. The only thing I wish is that we could see what things changed the next go around. I guess that is why I keep rereading the books. In hopes of new battles, new experiences, and new ways to the tower.

i thought it seemed like too easy of a way to end the story that took so long to read. but after thinking about it, i started to think that nothing would have been good enough to put at the top. it fits.
