Really, my summary says it all.

It's a cute premise overwhelmed by its need to be cool at the expense of plot, characters, meaning, or consistency. It has philosophical and literary pretensions that come off as kindergarten philosophy at best and ham-handed at worst. Luckily, these can be ignored fairly easily.

Good action sequences for the most part. Most of the cast is summer-movie capable. i.e. Their acting is neither embarrassing nor impressive. Keanu gives his second-best performance ever (after Bill and Ted's Excellent Adventure). Unfortunately, that is likely merely the convergence of his naturally confused look with the confusion inherent to the character.

All things considered a fun action movie provided you don't buy the hype telling you that it is so much more.

By the way, stop with this one. This movie is watchable and complete in its own and is only degraded by its truly dreadful sequels. If this movie is the triumph of style over substance, its sequels are the cruel beating and maiming of substance by style gone bad.
