Since you used the word "cliche" like 40 times in reviewing the Book of Eli (which really didn't feel that way at all to me), and gave it a half-nod regarding Avatar (which was generous), I'm rather expecting you to be consistent in your criticism of cliches.
So why give a complete pass on The Military Industrial Complex as the big baddies here? That has been _done_to_death_. It was old in the 80s when this was a miniseries, and it surely hasn't gotten fresher with time. In fact, I'd be challenged to find a time when there wasn't a movie in the theaters doing the same thing. At least State of Play put an interesting spin on it.
Granted I haven't seen it yet, so maybe this has some interesting twist too. But I need another 50 tote-Bible-across-the-apocalypse movies before it's anywhere near the cliche that this is.
