But even if it was, this series has a long history of borrowing from established box office hits. Just look at the first film, which started as such a ripoff of The Beast from 20,000 Fathoms that its working title was nearly the same.
I agree 100% on this. In fact many movies in a way started off as "ripoffs" but would become something original in of itself. Again I find it funny you mention Alien because that very series did the exact same thing. One of the staff (can't remember if it was writer, director etc) said he basically knocked off a bunch of sci-fi movies like The Thing. He said something like "I didn't steal Alien from anybody, but everybody." Just like Godzilla did with Kong and TBF2F. I am not saying "borrowing" from movies is always bad, but in this case it is as it really serves no point other than to capitalize on the fame of IJ. There are some exceptions where capitalizing on a trend or whatnot CAN ironically create something fresh and interesting, it's just that this movie was not of those exceptions. With all this said while I do stand by that I said this movie is the worst in the Heisei series it is far from the worst in the whole franchise and does have some entertaining scenes that can get you by on a boring day.
