The Daniel Craig Bond films.
I'd previously seen Skyfall (which I remembered as good, with my impressions dominated to an outsized extent by the house) and Spectre (of which I had no memories at all).
I'd also gathered from general pop culture consumption that Casino Royale was regarded as very good and Quantum of Solace as very bad.
What I took from watching all five of these in sequence over a few weeks is that they do basically all fit together - not in that perfectly crafted 'aha' way that some series do, but in a way that even when the seams show, by the end it feels like there's enough stitched-together integrity that it satisfies, including on the emotional level.
There's tons of action (QoS includes chases by foot, car, boat and plane), some memorable supporting characters (and some less so) among whom Eva Green's Vesper Lynd earns the heavy narrative and emotional weight her character is made to bear across films 2, 3, 4 and 5, dapper Dave Bautista's villain is enjoyable, and Ana de Armas' cameo also stands out, and some artful touches throughout in script, direction and cinematography.
