I don't think anyone was patronizing you, I am no expert on any of this but yes I am sure TOEI pushed for Star Wars like elements to be included in Message From Space to make $$$. That in no way makes Message from Space a carbon copy of Star Wars. Message from Space is actually fun to watch and not a non stop commercial for over priced action figures.
Star Wars, It's creator and the other two hacks that made Raiders & Terminator pretty much destroyed fantasy cinema in the US and ushered in the horrible world of the "Event Film" AKA the "Blockbuster" AKA "Garbage".
I have nothing good to say about Star Wars.
