Another thing that had my eye's rolling was the duel at the end.
You're not going to duel up a tower, it's impractical as hell.
You CAN'T surf on lava and fight because you'll burn to a crisp. The temperature that close to lava would have them passing out in very short order. Plus they both happen to surf? Yeah - i'm sure that's a new jedi power 'force surfing'. Then it ends with 'i have the high ground'? Why jump over him? Go left, right, other side, whatever. Jump 10 feet to the side, run in an continue. Except that, give the temperature down their you'd already be passed out on your mini surfboard.
Ultimately it fails because the two biggest things it was supposed to portray: The friendship between anakin/obi and anakins fall just weren't there. The space battle can be awesome, Ian can turn in an oscar caliber performance - but the bits of good don't compare to the gaping misses.
Capped off with 'dying of a broken heart'? (Puke). I'd venture that everyone woman put in the same situation gains strength to protect her kids. Every damned one. Just let the force choke break something they couldn't fix in time.
