I thought ID4 2 was ludicrous, but this one surpasses even that.
What shocked me the most, was not even the premise of the moon being hollow and created by aliens, which I think is actually a genuinely interesting concept, but how unintentionally hilarious the dialogue was, as if Emmerich was hopped up on shrooms when he wrote it.
It literally ends with a hologram of an elderly woman saying to a fat guy “You are part of the moon now.”
