Tim Brennan’s Rise from Boulder Critic to National Film Authority

For over a decade, Tim Brennan has been one of the most important voices not only on AboutBoulder.com, but across our entire media network. With thousands of loyal readers and a Rotten Tomatoes–certified critic badge to his name, Tim has shaped the way Coloradans — and moviegoers across the country — engage with film.

Tim didn’t just grow up in Boulder — he grew into one of its most respected writers. From indie hits to Hollywood blockbusters, his reviews are honest, sharp, and always insightful. Over the years, his work has driven some of the highest traffic numbers we’ve seen across our network of local city sites. He’s not just a writer — he’s one of the key reasons AboutBoulder.com became what it is today.

And here’s the real kicker — Hollywood notices.
It’s become a regular occurrence: publicists, studios, and filmmakers across the country reach out asking one question — “Can Tim Brennan review our film?” From major motion pictures to high-profile indie premieres, Tim’s name is on the shortlist of reviewers people want. That demand says it all. His reputation isn’t just strong — it’s sought-after.

Today, Tim stands among the elite. As a Tomatometer‑approved critic, he’s part of a select group of national film reviewers whose opinions help shape the overall Rotten Tomatoes score. His byline has become a go-to for both casual movie fans and film buffs alike. His words carry weight — both on a national stage and right here in Colorado.

Tim’s influence now stretches beyond Boulder. His reviews are featured not only on About Boulder, but across our broader network of sites, connecting with readers in Denver, Colorado Springs, and beyond. And still, he remains deeply tied to the community that launched him. His RT bio says it all: “He grew up in Boulder. Went away for college. Came back. Stayed.”

One of Tim’s most recent reviews of The North called it “a low key masterpiece” — and that kind of simple brilliance is exactly what makes his writing so resonant. You don’t just read a Tim Brennan review. You trust it.

So today, we take a moment to say something he rarely does for himself: Thank you, Tim. For the words. For the hits. For the countless nights you watched so we didn’t have to.

You are — and always will be — one of About Boulder’s greatest success stories.
