Like milk gone bad

There have been a few sequels where producers have let things go on WAY too long before they shoot another one. Now usually a sequel is dependant on the original film doing well. Most times a sequel is made within two or three years. But not all the time. I think there should be some kind of cut off where it's too late to make a sequel. Let's take a look at some films that had some huge gaps in between.

Major League 1 (1989) Major League 2 (1994)

Major League is one of the most under-rated sports films ever. Granted it's not a classic by any means, but all of the characters are original and funny. However, when Major League 2 came out things seemed a little different. For starters, Charlie Sheen (aka Carlos Irwin Estevez) had put on about ten to fifteen pounds, Tom Berenger went from having curly brown locks to lots more salt and pepper up top. Plus in his face it looks like they peeled him out of a gutter after a bender, threw some jeans and a blazer on him and told him recapture the magic of "Jake Taylor". Problem is he went from looking 38 in ML 1 to 58 in ML2. Plus they had to replace Wesley Snipes in the second one with Omar Epps. I like Omar Epps, but it's too bad that the character of Willie Mayes Hayes went from a guy in his 30's to a guy who looks like he is about to finish his senior year at high school.
The owner of the team Rachel Phelps also has aged noticeably and for some reason they decided to film it at Camden Yards in Baltimore (movie is supposed to take place in Cleveland) and they just hang two banners in the closeup outfield shots that read "Cleveland Stadium" to make it look 'authentic' and fool you.
Genius.

Back To The Future 1 (1985) Back To The Future 2 (1989)
Back to the future is the greatest movie ever made. I think I have made this clear to anyone who knows me. Sure the ride at Universal Studios is violent, and makes you sick but I digress. Four years for a sequel isn't too bad, but it's pushing it. Sure Marty doesn't look like an 18 year old anymore, but I can let that slide. But they replaced the original Jennifer with Elizabeth Shue. Elizabeth Shue with red hair doesn't work for me. I love Shue, I do! But only with blond hair. Plus they had to write out George McFly because he wanted Noah's Ark. Instead of it filled with animals, he wanted it full of cold hard cash which he never got. It's a shame because he was such a kick ass character and so important in the first one.

Basic Instinct (1992) Basic Instinct 2 (2006)
What's the difference? Sharon Stone at 34 and Sharon Stone at 48...nuff said.
Sure she still looks hot for a 48 year old, but makeup, lighting, cgi, holy water and body doubles can make anyone look good.

Even this guy
