If the pop powerhouse Wham! didn’t begin, progress to the “Top of the Pops” and end exactly this way — and it almost certainly did — it most certainly should have.

Chris Smith’s engaging, adorably upbeat portrait of the brief, brightest flash in the pan that was Wham! is mainly comprised of just two voices, the late George Michael in the extensive collection of archival interviews he did, and a present day remebrance from his “best mate,” his friend “from the age of 12” and Wham! co-founder, guitarist and fellow songwriter Andrew Ridgeley.

That narrow focus allows the film’s sunny disposition. None of the messiness and trauma of Michael’s later life and untimely death is here. That’s for other documentaries. This is just collaborating, performing, doing joint interviews and having a good time all along the way.

“What!” brings Ridgeley out of Michael’s shadow and into the spotlight where he comes off as a devoted friend, valued collaborator and the member of that group determined to make “a graceful exit” from that exhuberant, rowdy and stunningly successful performing group of their shared youth.

They made their “graceful exit” after a race to the top, with each of them the ripe old age of 23.

The chart-dominating Wham! was only together for four years. But it was a metoiric rize for two North London lads “fated” to to form “a brotherhood” from the moment twelve year old Ridgeley took “the new boy,” Georgios Kyriacos Panayiotou, under his wing to show him the ropes at Bushey Meade School in 1975.

Using home movies, primitive promotional videos (and outtakes) and TV appearances and live concert footage, Smith — who gave us “Tiger King” and the documentary about the symbiosis Jim Carrey achieved playing Andy Kaufman in “Jim & Andy: The Great Beyond” — paints a picture of two devoted determined to make it as a team and the odd, fate-kissed path that brought them success.

“Wham!” paints Ridgeley as the guy Michael credits with coming up with the group’s name and their first song, “Wham Rap,” the inspiration for “Wake Me Up Before You Go-Go,” and their visual style. And most touchingly, it shows Ridgeley — in joint interviews back then and even now — as perfectly willing to take a back seat when it became obvious the pal he always called “Yog” (a shortening of Michael’s real name) was a genius at creating power pop sing-alongs and romantic ballads, writing, singing and producing them.

Ridgeley was also the one who considered their chart-topping group a phenomenon of youth — theirs, and their audience’s. That “bow out gracefully” thing was, he figured, the perfect way to “break up.”

None of this Simon & Garfunkel sturm und drang, none of the bitterness of most every other group — even siblings like the Everly Brothers — that came to an end.

They agreed to do a final Wembley Stadium show at their peak, in 1986. And “The Final” was their finale. Michael’s later death merely ensured they’d never be tempted into doing a “reunion” tour.

The film’s narrow focus — with only their manager, Simon Napier-Bell, appearing here to offer a slightly more objective take on the group dynamic, the psychologies behind their success and their decision to move on — renders it quite myopic.

Little revelations about the “political” climate and nature of their earliest songs, an antidote to Thatcherite Britain, can surprise. The “I’m gay” realization of George and how he told his friend is almost wholly lacking drama, because Ridgeley and Ridgeley’s ex-girlfriend, a singer with the group, were nothing but supportive.

And yes, that ex-girlfriend was there for the whole ride.

I’d have loved to hear from “the girls” they brought into Wham! who became a part of the stage show, the music videos and background vocals at times. If nothing else, they could have provided insights into the true nature of the team at the top.

But Smith has made a film that’s not unlike Wham!’s hits — bouncy, light and frothy, nothing that demands anything of the viewer and listener other than a smile.
