Except for the awesome scenery, part three of Michael Winterbottom's culinary travelogue with the often funny duo of Steve Coogan and Rob Brydon, is tedious.

Ever traveled to a beloved city or country multiple times and noticed how the magic dissipates as the novelty wears? Well, my weary travelers, that in a nutshell is “The Trip to Spain,” the third of Michael Winterbottom’s “Trip” triptych about actors Steve Coogan and Rob Brydon playing exaggerated versions of themselves while on a culinary tour through some of the most beautiful European locations imaginable.

What was once fresh and tasty is now stale and largely flavorless, a going-through- the-motions exercise in what can only be described as a money grab. What little fun remains rests largely in the charm of our two self-deprecating traveling companions. Their appeal cannot be overstated. But like a house guest who overstays his welcome,  animosity starts to set in before eventually festering. That’s when you can confidently say the franchise has finally jumped the shark au poivre.

That moment arrives roughly one hour into this butt-numbing 105-minute indulgence, when the duo’s non-stop – but still funny – voice impersonations of the likes of Roger Moore, Michael Caine, Mick Jagger, Anthony Hopkins, John Hurt, et al., yield to a considerably more melancholy mood, as the boys start to reflect on their age (both are in their 50s) and missed opportunities.

It’s a drag. And it only gets worse when Coogan’s on-screen son telephones with shocking news that will greatly alter both their lives. Coogan’s elan wanes further when his half-his- age girlfriend delivers even worse news – and that’s before ISIS shows up. By then, the only test “The Trip to Spain” passes is the one on your patience. For the first time in all those hours spent with Coogan and Brydon traversing the North of England in “The Trip” and the west coast of the Boot in “The Trip to Italy,” I was finally spent and ready to head home.

And I probably would have if not for the awe-inspiring scenery, most of it shot along the gorgeous Spanish coast by the keen-eyed James Clarke. With its unique blend of mountains and sea, Spain is easily one of the most beautiful countries in the world. And the architecture . . . . don’t even get me started. It’s a place to die for, from San Sebastian to Cuenca to the movie’s show-stopper, Malega.

In between we learn much about the Moors and their cultural influence through Coogan, per usual, fighting to be heard over Brydon bombastically impersonating another Moore, this one Roger, talking about his brother, Les, because as we all know, Les is Moore. If that strikes you as funny, you’ll like “The Trip to Spain” far better than I. No one, though, is going to break more than a pained grin when the pair dress up as Don Quixote and Sancho Panza in the legendary pair’s hometown of Almagro, where our Anglo visitors make a regrettable aside about tilting at turbines (which dot the landscape) instead of windmills.

No doubt, these bits are cringe-worthy, but they’re preferable to the sappy third act when egos take a beating and Brydon has his usual epiphany about how much he misses his family back in London. What’s funny, speaking of egos, is Coogan, who never wastes a chance to boast – Trump-like – about his two Oscar nominations for writing and producing the lovely “Philomena,” a 2014 film that also earned him an audience with the pontiff. But even His Holiness becomes fodder for cheap gags. Is nothing sacred? Is the pope Catholic?

More to the point, is this dodgy movie worth visiting? Only if you’re bored and have nowhere else to go.
