Most people criticise the dinosaur models in this story for the way they look, and their lack of movement, but I think far sillier is the way they sound. The T Rex is actually saying the word "RAAAAARRRR", like it's really a terribly cultured and refined dinosaur merely pretending to be a carnivorous monster from the dawn of time. It's a bit like how children might play at dinosaurs in the playground!
Everything looks different in colour. Everything looks like low budget Doctor Who again, rather than the glorious grainy "found footage" monochrome film look of part 1 that made it feel like a lost home movie from the 1930s. I miss the eerieness of the black and white part 1!
