Neither the acting nor direction is particularly creditable.

Arriving from outer space (for which read Russia), a large ball of interstellar snot terrorises a small American town by eating everything in sight.

Unfortunately, [Harris's] picture talks itself to death, even with the blob nibbling away at everybody in sight. And most of his trick effects, under the direction of Irvin S. Yeaworth Jr., look pretty phony.

The Blob is interesting in how it welds together a monster movie with the sort of teen angst drama that was popular in the wake of 1955’s Rebel Without a Cause.
