It's easy to understand the fascination with the transition to land because that is, after all, our own ancestors whose route we are trying to decipher.

The human race has an innate narcissistic curiosity about itself, and it is from these first terrestrial organsims that we as a species eventually arose.  So it makes sense that this record is paid quite a bit of attention by researchers and enthusists alike.

These are the people who like to envision how it must have been back then.  To have a giant sandstone continent, on whose coasts and in the shallow freshwater lakes, the first vertebrates decided to make a major life change and slowly adapted to life onshore.

From beginnings as fish with lungs to tetrapods with their four limbs, the process of terrestrialization will never loose its popularity with our own species.
