What do you guys think of my movie idea?

I thought about this movie about this farmer who's wifey and kids are abducted by this supper space alien who crashed near his farm. The alien is kinda like predator. Actually he might as well be predator. So yea the farmer builds a bunch of weapons to go fight the alien. Does that sound like a movie you would go watch. We can use the theme from terminator 2 for when he makes his weapons from different farming tools. wait, better yet instead of the alien maybe it can be a terminator who was sent back to take out the farmer because the farmers son would be the founder of Cyberdyne systems competitor who puts cyberdyne out of business.
