Bolg is a giant much like Azog, now let's look at lurtz.

It seems to me that Azog was near Uruk Hai size, maybe a tiny bit bigger but not much. Which means that Gimli killed 42 Uruk hais while a party of 13 and a wizard and a stealthy hobbit couldn't deal with a wolf pack of what...15 orcs? Yeah I think also that if Jackson wanted the dwarves to be running throughout the movie, he should have equipped them poorly. Then maybe armed them when they got to dale...but as it is now, 13 warriors and a wizard is running from 13 orcs. Gimli a less battle hardened dwarf killed 42 Azog sized uruks at the battle of helm's deep.
The movie doesn't make much sense, they spent ages making it yet I have seen more thought through movies made by people in less than a year. Something went horribly wrong when they made this movie, I wonder who is to blame if not all of them. In the lord of the rings trilogy one could nitpick a few things that was done badly. But they aren't wholly bad movies, the hobbit part one deserves to be REMADE as it stands now. It's horrible, truly horrible. It's kind of pathetic to be crying about it like this, but it's kind of annoying. Anyone on this forum would be able to do it better I'm sure...
