David O Russell's latest - a shaggy dog mystery with a deliberate air of penny dreadfuls - could do with more straightforward narrative and fewer screwball convolutions.

There is much in Avatar that is broadly drawn, clichéd even – but it is also these very things which might just earn it the status of a classic.

Ponderous but glorious.

Directors Joe and Anthony Russo use the length to explore more than one significant theme in depth and to shift tone markedly from hour to hour.

Infinity War is a clearing of the decks: opportunity for new characters and plots to emerge; opportunity too for some characters to move on.

There is a distinct lack of energy and focus especially for the first hour, when nothing much happens.

Imagination breaches the boundaries of wonder

Audiard has assembled a remarkable team of actors

The baddie's been beefed up, the plot's been pared down, but the emotional core which really sold the first film—the magnificent character interaction—remains unscathed.

Spielberg's direction is delicate, but very relaxed.
