Krapp's Last Tape

Well hopefully it's his last tape.
For a play, I didn't understand it at all. Didn't like it, and for literature, it really had no point. I do not know why Krapp would listen to one of his old tapes, it just confused me. He was probably trying to listen to his memories and remember what he thought of the woman in his life. He got sentimental when listening over his memories of the woman. Krapp seemed to be an aggressive man, but when listening to the memories of the woman, his face changed. By going by the name of the play, if it was his last tape, then he was probably going to die soon.
The tape did not make sense at all. If the play did have a point then I think it was about someone listening to their memories, like when someone reads their diary to reminisce those memories.
