A scene from Guardians of the Galaxy Vol. 2.

Trippy Marvel fun continues with Guardians of the Galaxy Vol. 2, a big, nutty, spiraling sequel that brings the fun—along with a lot of daddy issues.

Star-Lord, aka Peter Quill (Chris Pratt), had him some major mommy issues in the first movie; this time out, dad takes a turn at messing with his head. Dad comes in the form of Ego (Kurt Russell … yes!), who we see hanging out with Quill’s mom in the 1970s during the film’s prologue. (Both CGI and practical makeup were reportedly used to de-age Kurt Russell, and it looks great.)

After a killer opening-credits sequence that features a battle with a giant slug thing while Baby Groot dances to Electric Light Orchestra, the Guardians—Quill, Baby Groot (the voice of Vin Diesel), Gamora (Zoe Saldana), Drax (David Bautista) and Rocket (the voice of Bradley Cooper)—find themselves on another quest. They are quickly diverted to Ego’s planet, where Quill finds out more about his celestial origins.

Russell proves to be perfectly cast as Quill’s bombastic father, as Pratt possesses many of the legendary action film star’s alluring traits. Seeing them onscreen together—at one point playing catch with an energy ball Quill conjures with newfound powers—is one of the film’s great joys.

That scene also proves to be misleading, as writer-director James Gunn isn’t going to settle for an easy story about a wayward son reuniting with a dream dad. As it turns out, Ego makes Darth Vader look like Mike Brady as a father: Vol. 2 is as dark and nasty as it is silly and action-packed.

Quill’s daddy issues don’t end with Ego. Oh, no, that would be too easy. Gunn and his cast have come up with a story that is far more complicated than that of your average comic-book movie. Of course, there’s also the whole sibling-rivalry thing between Gamora and her twisted sister, Nebula (Karen Gillan). When these two fight, it goes way beyond kicking each other in the shins.

Another subplot—the film has quite a few—involves Michael Rooker’s disgraced Yondu looking for redemption. This storyline results in one of the greater surprises offered by the franchise so far. Rooker, an underrated actor, makes Yondu’s journey compelling.

All the story threads hold together well as the film ratchets up the action at a frantic pace that Gunn always manages to keep under control. The director has a way of going crazy with his visuals and pacing—yet making it all comprehensible and coherent.

Bautista, good in the first film, graduates to greatness here, providing most of the film’s big laughs. His newly minted relationship with Mantis (Pom Klementieff), Ego’s travelling companion, and his frankness about her physical appearance make for one of the film’s great running gags.

Sylvester Stallone makes a brief appearance as a renegade thief; while he doesn’t share screen time with Russell, we’ll just go ahead and call this a Tango and Cash reunion.

A couple of years back, Yes album cover illustrator Roger Dean took James Cameron to court, claiming Avatar’s production designs looked a lot like his work. He might want to fire up the lawyer brigade again, because Ego’s planet looks like it was completely inspired by Dean’s paintings. Whenever there was a pan of the planet’s landscape, I had Yes’ “Starship Trooper” playing in my head.

While Yes doesn’t make the classic-rock soundtrack, songs like Fleetwood Mac’s “The Chain” and Cheap Trick’s “Surrender” do. Like its predecessor, Vol. 2 works as an ode to classic vinyl rock.

The Guardians will be back in another sequel, along with an appearance in next year’s Avengers: Infinity War, so the fun is just beginning. As always, stick around for the credits; there are scenes still to be had after the main movie is over.

Guardians of the Galaxy Vol. 2 is playing at theaters across the valley in a variety of formats.
