Confused

I had a difficult time reading this play. I found it very confusing and sometimes pointless. While I did like listening to Estragon and Vladimir go back and forth during some conversations, I did not completely follow them at times. Pozzo and Lucky were an interesting duo though. Pozzo was horrible to Lucky, and Lucky just took all of the abuse, and his reasons why were not totally clear. I actually do not like Pozzo at all and felt bad for Lucky. Near the end of Act 1, Estragon and Vladimir talk about hanging themselves again, and they keep mentioning the rope. Was that suppose to allude to Lucky in some way? When Pozzo went blind in Act 2, I was happy because it meant that Pozzo had to rely on Lucky for something for once even if he is still unappreciative. The ending of the second act was basically the same as the first act's which means that Estragon and Vladimir are stuck in this repetitive cycle of waiting for godot for as long as they live. Either way, I'm still confused as to why this play is successful as it is. The language was confusing, and the message was not completely clear to me. Perhaps the discussion in class will clear things up for me. Until then, I'm lost.
