It's a different experience. I've gotten so comfortable writing SG-1 that I forgot what it was like to have to struggle with new characters. It's frustrating but exciting at the same time. I have to think different and I have to write different. Will it be my best piece of work ever? Probably not. But it's forcing me to push the boundaries, which in the end will only help me with my own writing.
Now, I don't want to make this a habit - I can't get too involved in fanfic in any fandom because of the original stuff I am working on. But watching Supernatural and working on a plotty story for it on my own has been relaxing. I really need an escape right now and it's working well to soothe the savage beast within me.
Of course, I can't wait for the new SG-1 movie coming out in March or the X-Files film this summer. But for now, watching this show is giving me an outlet and I appreciate it. I so need it right now.
In the end, it makes me happy and that's all that is important.
However, if you like SPN and want to read a hilarious fic, I highly recommend Out of Mouths by eve11. OMG. I don't normally read SPN fic, but I trust her writing and this fic was funny, crazy, and in character. Totally awesome for her first SPN fic ever.
I have a couple of others I want to read (and promised to read) but for now, I say go read this one. Haha.
