>>1996Hardly. Star Wars got big because it combined a simple easy to digest story, with pretty spectacular visuals that blew pretty much anything that came before out of the water. Thrown in an enjoyable easy to expand on universe that millions of tards like us got into, and you have a recipe for a giant success.
But sure, if it came out today it probably wouldn't be very well received and quickly forgotten. The acting in particular is pretty rough, and great special effects shows are a dime a dozen these days. It didn't come out today though, it came out in 1977.
