I especially loved "Before Sunset". I'm a bit worried that it will be tainted for me by knowing what happens next. But there's no way I'll miss "Before Midnight".
I'm reminded of
Fametracker.com. I miss them so much. They would have done such a great list of further sequels (complete with summaries): "Before Gloaming", "Before the Witching Hour", "During Midday", "After 4:20pm", etc. I don't have the skill to do it. Does anyone know a site these days that equals what they used to do?
