I have often argued that endings are overrated in determining the value of a story.
For example, I think
LOST was an (overall) awesome show. Some people argue that the ending and lack of answers "ruined it." I argue that the whole point was they were lost all along and any ending involving "finding answers" would have been worse (and to the degree they tried to give answers in that ending is what made it awful). I simply have never re-watched that ending, but have enjoyed part of the previous seasons over and over.
This is out of date now (esp. given Adnan Syad's recent freeing from prison), but I explored the idea of endings using
Lost and the
Serial podcast back in 2014:
