No, the ending betrays everything the creators promised up to that point. Lost was made right when TV shows got really good, so you have much better options to choose from now. I've watched all the seasons, appreciated the online stuff they did at the same time, but still I recommend you don't watch this show, it's a waste of time.

This gif makes more sense than the show ultimately did.
It's such a waste too, because the actors, the story, the music, everything was so great (for a TV show at the time), but in the end it's all bullshit because the writers didn't know where to take it. I won't spoil the big reveal, since you asked not to in the opening post, but please, watch a better, more recent show instead.
