How many of these non-fans actually watched the original trilogy? I find it hard to believe that, having seen the original trilogy, there is any opacity in tPM's plot.
Well, all of them. The undergrad in question nearly wet himself in anticipation when I told him I had the trailer. He's a fan without being
one of us. Saw the OT on video as a kid, but it was after all the hoopla had died down. Then there's my father, who sat through the OT with me about a thousand times in my youth, is a reasonably sharp fellow, and enjoys the movies tremendously, but he didn't put it together entirely until Palpy's conversation with Anakin in AotC. He thought Palpy "was up to something" in tPM, but didn't think he was Siddious. Remember, in the OT, the Emperor was "the Emperor" NOT "Emperor Palpatine." You only saw that name in the novels and some of the other tie-ins.

A double-bladed lightsaber works, because it can cut at any angle
Which makes it very, very hard to use in real life, because most of those angles are just as dangerous to you as to your opponent, if not more so. It would be too dangerous to use, realistically, and the fact that you can only grip it in the middle takes away the primary advantage of a staff, reach. Every staff technique I've ever seen relies upon grips that are impossible with that beast.

I thought Maul's combination of a staff-fighting type still and Wing Chun was fantastic visually.
It was. And I loved it when I first saw it, but once I took some martial arts it became increasingly irksome. It's not so bad when he was 1-on-1 with one of them, but when he was fighting both jedi, there are too many moments where Ewan McGregor visibly hesitates to wait for Park to get his blade into place and what not. It's just not possible to use that "weapon" efficiently.
Lord Pendragon said:
Indeed, it made it all the more jarring and silly when Maul died, because he'd been so badass up until he needed to be killed.
Well, sure. He had to be bad-ass to overcome the severe limitations of that weapon.

I personally found him to be much more impressive when he was using only one side of the thing. I REALLY wanted to see more of that first fight in the desert with Qui-gon. The use of a single blade with that really long handle was cool. And the additional leverage would be nice.
Similarly, people keep complaining about Dooku's "bent lightsaber." I don't see the problem. It's not like the blade was curved. And there is a precedent for curved handles in swords. Arguably, it merely makes the lightsaber into a one-handed sword instead of it's typical sort of hand-and-a-half usage.

The Star Wars game
Knights of the Old Republic II has a villain who uses such an attack, though, and it seemed dramatically viable in the game.
Let me try to explain, though this is difficult without visuals. I've got my lightsaber floating a foot or so from my body. You swing at me. My lightsaber flies into place to deflect your attack. For an instant, our blades are crossed in front of us, a la the old Luke vs Vader duels. Then, the handle of my blade swings towards you and down, using it's point of contact with your blade as a pivot point. If my arm was connected to it, you could kill me instantly, because the entire side of my body is exposed to you with no defense, but since my sword is floating free, I
might need to take a step back, but in the meantime my blade has made a full revolution and taken your arm off. Or your head, if I had picked that angle. Even if I had to stay within 12 inches of the lightsaber at all times to maintain control, without an arm attached to it to limit movement, the sword can do all manner of things that make it invincible.
This is why I don't believe in animated swords in D&D, either. It is impossible to defeat them, with any sort of verisimilitude.
