No Yoda being able to call down lightening is stupid. If he could do that then he could have taken out Vader and Palpatine himself in RETURN OF THE JEDI without Luke.Ah, you're right. Luke holding a lightsaber is stupid. But Yoda being one with the force definitely makes sense he could conjure a lightning bolt to teach Luke a lesson.
ET's not in The Phantom Menace anymore? Movie's ruined. George Lucas ruined my childhood!
and yes the ET's are gone. They were only able to bee seen in the in the theatres during the original release and when it first hit VHS. It did not hit DVD until almost a year after the VHS release and when it did the ET's in the senate were gone never to be seen again on any other future release.
