With this news popping over the web I actually re-watched the original Spaceballs today to reassess the quality, since I remember being underwhelmed last time I watched it, and after a re-watch I have to say, it was ... well, it held my attention. There were a few funny moments throughout, but pretty much the only thing I found consistently funny were the repeated jabs at Star Wars' merchandising. A lot of the jokes were cringe-worthy puns, and others just don't make any sense at all. One of the characters, a clear reference to Yoda, is called Yogurt, and I'm left wondering where the joke is. Yeah, okay, both words start with Yo-, but where's the joke?
Some of the best moments, in my opinion, came from the 4th wall breaking jokes like the stunt-double scene, but overall I just don't really care for the type of humor in Spaceballs and I'm not really sure why.
