If you must remake 80s movies, then remake THIS one
I'm generally not in favor of remakes because it shows such a lack of creativity and because the remakes usually suck balls (looking at you, Karate Kid).
However, I saw this movie not long after it came out and remember thinking that it was a so-so movie. It would have been better with a better cast, except for Robert Preston, and with more realistic FX.
So yeah, I definitely would be interested in a remake, especially with the resources we have now. Imagine better cast, less 80s cheese, and professional advanced CGI...the death flower would be even more awesome.
