Alpha, a spectacular prehistoric eye-candy survival yarn, is enthralling in a square and slightly stolid way.

Enjoyably old-fashioned in its narrative but crisply modern in technique, it is engaging enough even for those of us with no soft spot for pets.

Alpha is not a perfect movie, and it is occasionally a way-too-pumped-up pulpy one relying on big-budget bulk. But it is most certainly a tonic in an age when every blockbuster film feels like part of some endless multiverse-cum-marketing scheme.

Alpha (think Bear Grylls’ meets The Incredible Journey: Ice Age Edition) is a welcome end of summer surprise that will tug at the heartstrings and delivers a visual spectacle that will wow. It’s just a shame that it tips more towards spectacle over substance.

Alpha has been sold, to some degree, as a family-friendly film, and while it’s too violent and perhaps too heavily subtitled for young kids (or, for that matter, some adults, who may notice how superfluous much of the dialogue is), it’s easy to picture some 10-year-olds taking to its exciting, cornball charms.
