There’s a very thrilling documentary hitting theaters this Friday entitled “Dinosaur 13,” about the most complete T. rex fossil ever found and the intense battle that ensued over who owns it.

It’s crazy stuff that will really make you think…and make you miss the greatest dinosaur franchise of all time, “The Land Before Time.”

The original “Land Before Time” was a 1988 theatrical release helmed by Don Bluth that became such a smash hit it spawned 12 direct-to-home-video sequels between 1994 and 2007.

That means there are 13 of these movies — the same number in the title of the new documentary’s title.

With so many iterations, we were intrigued enough to determine which one was the best.
