From time to time, I see threads on this site asking questions about MLP Generation 5. For those somehow unaware, the current generation is number 4, and the generations leading up to it are generally agreed to suck ass. In fact, FiM's success is still treated as an anomaly to this day. A happy accident akin to winning three lotteries with the same ticket.
Bronies like to treat the hypothetical Gen 5 like it will be a continuation of FiM. It won't. When Gen 5 comes, I'm sorry to say that it will be a fresh lottery ticket with the same near-zero chance of winning. New cast, new characters, new setting, new marketing, and that's if it gets a cartoon at all.
What we have right now is basically what Scooby Doo had for two seasons. After sucking ass for upwards of 40 years, Mystery Incorporated sprung up out of the blue and was miraculously very good. They made two seasons, and will never produce another episode again. And now the next Scooby show looks like it'll suck ass.
Be happy that we're on season 6 with no end in sight. Don't tempt fate by putting all your money on a number that probably doesn't exist anymore. We got lucky. Savor it.
