This is a damn good movie for a 1969 release! Of course the special effects are what makes it so good. Once again, I represent the one percent of the critics who liked it. I also have an artistic eye though. I see Harryhausen's Allosaurus(not Tyrannosaurus) as a living breathing beast. The only other movies that this happens is, One Million YeARS b.c. and Jurassic Park who's computer animation stands alone compared to the hundreds of other horrible excuses for c.g.i. that exist. With Harryhausen's effects we are talking about one artist who creates all the monsters and scenes, not about a team of people with different ideas who work on computers to make a flat representation of life. If you like movies like Anaconda and Tristar's Godzilla, then this movie is definitely not for you.
