Metacritic reviews

The heroes may be teenagers, but The Blob, though generally a goofy and enjoyable B-programmer ideal for watching while loaded in the middle of the night, is still one of the most pointedly reactionary of the 1950s’ alien-invasion movies.

A fun ride all the way through. [30 Oct 2008]

Despite producer Jack Harris' pooh-poohing of the 'political subtext' theory, rampant Commie-phobia pervades as the ever-redder blob sucks the life-blood out of every sacred American institution, climaxing in a truly marvellous scene in which the enemy within devours an entire diner, over easy, with a side salad and fries to go.

Whatever its flaws as a film, a none-too-scary monster chief among them, The Blob is a uniquely compelling monster movie.

Clever, tongue-in-cheek and far more fun than the hi-tech remake. [05 Jan 2003, p.8]

It is truly providential that a new horror melodrama called The Blob is so woodenly presented on the whole, for a little astute showmanship applied to such a plot would have been enough to scare the quills off a porcupine.

Neither the acting nor direction is particularly creditable.

Jack H. Harris, the cheapie producer who went on to make the forgettable Mother Goose A Go-Go, struck it rich with this silly picture that gave McQueen his first starring role after a few supporting jobs in Somebody Up There Likes Me and Never Love A Stranger.
