Was the end of Kindred satisfying or disappointing or a mixture of both?

The ending
of is somewhat unsatisfying, because the reader and Dana never find out
what really happened.  By the , the reader already knows that Dana lost her arm in a strange and
almost supernatural incident.  We really want to find out what happened.  We read the whole
book, and we learn about Rufus grabbing Danas arm and Dana killing him, but we do not actually
find out what happened after that.  She goes to the future, and by researching the past she
learns that his death was attributed to the fire.  She never really finds out what else
happens.

On the other hand, not telling the reader everything can also be
satisfying.  This way, the reader can imagine things and try to determine for his or her self
what happened after that.
