What is a good movie-making system thing?

On my computer I have windows movie maker or something and I'm guessing its not as good as other movie/video creating systems. I was just wondering if there is an awesome movie making system that is easy to use to not totally expensive ?

Im not sure if that made any sense, but hopefully it did

There's a software from adobe that's good, but is a bit more expensive...have you tried searching on download.com or reading something like pcworld.com for recommendations?

Some good recommendations here:
