I surprisingly had a ton of Zeo toys and figures and kept up with the show quite strongly. I thought the Machine Empire and suits were a step down from MMPR (but I was also quite attached to those), but I thought the actual story and characterization was stronger than anything in MMPR.
I tried to stick with Turbo, but I missed one episode and came back to find basically the entire cast had been replaced with characters I was unfamiliar with. I basically dropped it at that point, but did still have quite a few toys. In hindsight, I should have stuck with it, because rewatching it all years later I fell in love with In Space, Lost Galaxy, Time Force, and many other seasons. I think I was just burnt out and losing the entire cast I was familiar with was too much for me at the time.
