I wouldn't have a problem with a 20-year Death Star ... had the Empire not nearly completed a bigger, stronger Death Star in the span of six months to two years. The Death Star shouldn't have appeared in this film ... seeing the construction plans in Palpatine's hands would have been more than enough.

OK ... and if over-confidence was the issue, then why didn't ben just yell, "No, Anakin ... you'll never make the jump!" Tossing out some vague new battle strategy involving "high ground" is, at best, another awful choice of explanatory dialogue. At worst, it's a cop-out.
