It sounds like you are quite fed up already Druid Viking.
Well, hang in there, there is hope still
Basically they want X and you want Y. As their GM you have an obligation to make their time worthwhile, yet what is the point in GMing if you hate every second?
You need to think about some things:
1. Make a world pack (Check out the main site, look for the user MoonHunter in the article section). Give the world pack to the players and say: This is it. This is how it works. Can you guys live by these rules?
2. Ask all your players what they enjoy in regards to roleplaying. Make a list and treat their desires with respect. If your player says he thinks that being a Drow Ninja Katana wielding Neo-clone is awesome, respect that. You should respect your players. When you have their answers, try to satisfy their desires AND keep your integrity intact. Find ways to make their anime fantasies come true without making your game anime.
3. If all else fails you need to acknowledge that, as human beings, we crave different things. Take this site: Some come here to get inspired. Some comes here to be creative. Some come here to find friends and gain acceptance. Some come here to learn and get advice. Some come here to impress, and some come here to play by forum and have fun. It might just be that you are really looking for very different things. It might be your desires are incompatible.
Anyhow: Did you notice how the motives changed? It is the same with your group, and on multiple levels. Some players love the thrill of the dice roll, while other players love the theatre and drama. Some players love to immerse themselves into another world, another life, and they want to be in that virtual reality, what they ain't in real life.
So your players come to roleplay and they want to be whatever their heart desire. They might want to wear trench coats and wield a Dai-Katana and a wakazashi. They might want to run on walls and dodge bullets. They probably want to have fun.
It is your job to make them have that fun, but also to make them improve as players. With proper guidance you might make them do just that. So the next time a player wants to wield a Katana called "A thousand fiery blossoms", ask him if a Claymore named "The Eermoore Family Blade" will do... As it fits the description in the world pack better.
Give your players what they desire, but in your own way.
So to recap:
A)Create a world pack, a clear definition of the setting.
B)Interview your players, get to know what makes their day.
C)Shape their desires to your world pack. Satisfy their needs in your way.
D)If all else fails: Ruuuuun Forest, ruuuun!
