A review and an answer...
ok! I liked what I saw, just that there was so LITTLE of it! Anyway, do more and I'll be watching the whole thing. One guarenteed viewer here!
Anyway, You also asked for Ideas, so here goes a sample story line for you in outline form:
As we know, The SGC has been having probs with Apophis and such. He's coming to invade earth and stopping at each planet in the stargate network between here and Earth to "Reestablish dominion" over his empire. At each planet, there will be some new way that he tries to take over and SG1 must ATTEMPT to thwart him to no avail. Finally he reaches earth with a group of ships that no one could possibly beat, and multiple groups try to fight him. The Power Rangers, Goku and the Z fighters, even the backstreet boys! In the end, SG1 comes out with their puny army of fighters and tries to stop appophis and manages to destroy his fleet in a HUGE ass battle! However, It comes down to Apophis himself and a few hundred Guards vs. SG1! In some comical way, allow SG1 to outwit Apophis and you have made a kick ass flash series!
I hope this helped. If you want, contact me. I would be more then happy to work as a writer for you! I can't draw worth crap though, and I'm not very good with Flash, so writing a script is about all I can do...
