NOKW - Lord of the Rings 2

Here comes the next chapter in our "I'm Okay With, I'm Not Okay With" series (if you don't know what this is, click here for all of the past posts):

Movie:  Lord of the Rings: The Two Towers

Basic Plot:  The second movie in the trilogy has Frodo and Samwise teaming up with Gollum, meanwhile Aragorn, Legolas, and Gimli are hunting down the other hobbits.  Also, there is the awesome battle of Helms Deep.

I'm Okay With:  The fact that three of the heroes were trying to catch an entire army of orcs with no real back-up in case there was a fight.  The fact that a bunch of trees were able to take down Isengard in like five minutes.  The fact that Frodo would ever think of trusting Gollum to take them into Mordor without knowing that Gollum would definitely have ulterior motives.  The fact that spell-check is okay with pretty much every word from the Harry Potter series, but thinks every name and place from Lord of the Rings is misspelled despite that series being around since the 50's.

I'm Not Okay With:  The fact that Gandolf was able to beat the Balrog by using a sword and some wicked awesome magic, but then never uses any worthwhile spells the rest of the series.  Seriously, the Balrog is a massive, fire-breathing demon and Gandolf took down that guy like he was his bitch, but when faced against lesser enemies in the rest of the series, he generally just uses a sword and relies on others to take those bad guys down.  Don't you think that it would have come in handy for Gandolf to use some badass spell to help defend Minas Tirith?  Yes, it would have.  What about when they faced a cave troll in the first movie?  But no, instead he runs around killing orcs with his sword.  I am not okay with that.

"That tiny little guy in the bottom right is Gandolf. and yet he killed that monster taking up the rest of the picture."
