I sat in a cinema with some annoying commentators (2 boys and 2 girls, with some smuggled beer, I suspect). But they were annoying only at first time. Some of they comments were quite adequate... and may be fun... well when Skywalker has this dull "love talk" with the princess (whatever she was called, I don't remember for now), she goes like:"We'll have a baby..."
and the comments: "WHAT? Right NOW?!" Another voice goes: "But I've been at the military service for 2 years..."
Then they discussed why in the distant future they didn't know there would be 2 babies instead of 1... and so on.
