I know this will ruffle many feathers, but I'll say it anyways. The Disney Renaissance from 1989-1999 was considered to be a new Golden Age for Walt Disney Animation Studios. It was (and still is) a fantastic run However, it seems we're in an equally impressive run of films. I personally think it's a more impressive run because it's been going on for longer and shows no signs of slowing down. The 90's run was very front-heavy. They never reached the highs of The Little Mermaid, Beauty and the Beast, Aladdin, and The Lion King in terms of pop culture impact. While it's arguable those four movies are better than any of the movies out during this current run, I think the current run has been better overall. Most consider the current run to begin with Tangled, I however, think it should begin with Meet the Robinsons because that is where John Lasseter started overseeing Disney Animation (which I assume ended with Moana, following the fallout due to the reports of sexual harassment unless he still has a credit on Wreck it Ralph 2). I know nostalgia means a lot, but I just see what they've been able to do from 2007-2016 and think they have surpassed 1989-1999.
