Why some reboot films are good and others very bad?

Really it is. Enough said on that aspect of course. This article isn't just a article, but me explaining my personal assessment of rebooting a movie. And that's any movie. For the past five to ten years, we've seen movies get rebooted. Some need that reboot...others, well, let's just say need stay as it were to attain the label of being called 'a classic'. Now here's a few reboots that wasn't even deed a reboot...Total Recall with Colin Farrell. WTF? Was that even necessary for a reboot? What's wrong with the original one with the Arnold? What was wrong with original that warrants a reboot? Well, we seen what happen...new Total Recall was a complete and utter failure. Serious waste of good special effects and an storyline...Gee, how can I actually describe that bad after taste in my mouth. Puke material. Now, we have a reboot of a complete franchise of Sam Raimi's version on everyone's favorite web-slinger, Spider-man. I will admit...I'm a Marvelite. Always will be one and forever. Yet if you have a money maker and everyone going to see it..does it warrant a reboot? In my opinion, nope. Yet, everyone at the magical place of film-making think so. Why? Issue(s) with the original director? A lousy script? Too much for a budget? Or the best one, the leading actors want more money, yet our movie(s) is making a ton of money at the box office? We won't know the actually reason behind that mess/drama. But as a loyal Marvelite, I wasn't too keen on the reboot, no! I found the reboot slow, tiring and lacking the essence which many of us have love and relate to Peter Parker during the years. This one had too many subplots which was trying to be more than it seem. And gave me one nasty after taste in my mouth. Here's another one, the Great Gatsby...written by F. Scott Fitzgerald. I've read the book in junior high school. See both films back in the days, yet here's another reboot that was too damn dazzling with the lights and sounds from...what era? Oh yeah...this era. Too hip? Yes. Too much bright lights? Yes. Does it need to be retold? No. This is a movie that was made how many times? Five times...Yes, five times is norm here. What I'm getting at is the fact, is a reboot necessary? And another question, at what end does the rebooting stop? Is this going to be the norm? Should a good movie get a reboot when a executive or writer or better...A director comes around with his or her hands waving in the air saying..'I have a idea on how I see this (good) movie should be heading...'. Or better...'this is a bad movie...I can make it better...'. Come on now. Really? How this..it's the movie executives making the money. Our hard-earned money on sweat and blood at work. We at least deserved to be entertain...not blind as previous reboots have made themselves out to be. Again...hey, I'm new at this. And this is a commentary of me, being the Devil's Advocate here. Will I get new friends? Maybe not. Will make others think on reboot with a open-minded pov? Maybe or maybe not. But I hope it make the readers and fans alike to have a different aspect on movies and reboots. Instead of diving into a movie/reboot and not getting what you normally would expected. Are you getting your money worth or not. You have that God-given right to make that choice. Not me. Nor them (Hollywood). Just you.
