To me it's not really about how iconic a movie was or wasn't....If the powers that be in Hollywood think a reboot or remake will make money, it will get made. I'd just prefer that AT LEAST 35+ years go by before something gets recycled.
I just hit 40 so I'm finally starting to see movies I remembered as a kid get redone. Russel Brand was born to play Arthur so I get it. I doubt Red Dawn will be any good but I'll reserve judgement until I see it.
Let's go back to True Grit for a second.....I saw the original in the early 90's because I dig Westerns but that's not typical. I happened to love the original & the remake but I get how there is an entire generation out there that think it shouldn't have been remade. And there's another generation that couldn't sit through the original version if you paid them.
Bridge On the River Kwai is one of my all time favorite movies. To me it's iconic but I'd still love to see a modern version. WWII was all the rage in TV, movies & video games a few years ago so I say why not? But people who saw the original release when they were 30 probably hold it sacred because they were 15 during the war.
Same way my generation doesn't want to see The Breakfast Club or Ferris get remade anytime soon. But 20 years from now we will all give a wink and a nod when our Grand-kids think Breakfast Club 2030 is the best movie ever b/c it relates to their high school lives so much.
