When Dinosaurs first aired, I was very young, so I didn't see but maybe the last season. However, now that they've started to release them on DVD, I'm hooked.
Dinosaurs was way ahead of its time, in that they presented a family, much in the style of your garden-variety family sitcom, but they rolled back the clock 60 million years. They have many problems similar to the ones you would see elsewhere, only adapted to a dinosaurs point of view.
The humor in this show is what really sets this show apart. There is an equal mix of political satire, slapstick, and genuinely funny and sharp wit. Many of the laughs are provided by Baby Sinclair, who can say just one word and have you rolling with his impressive repertoire of catchphrases.
I highly recommend this show for any sitcom fan.
