I just did a re-watch on the IMDB channel on Amazon (which I think is free, since it has some ads, don't think you have to be a Prime member to watch). While I would rather have watched without ads, I didn't feel like subscribing to another streaming service to see it.

Lost is a show that just screams to be binged, since there is so much going on that watching the old-fashioned way (one episode a week, seasons spread over six years) doesn't do it justice. I really enjoyed the re-watch, since I hadn't seen Lost since it went off the air 10 years ago.

And as far as the ending goes, series finales are always tricky. Very few get it exactly right, especially since so many people want different things for the ending.
