anyone notice certain slot themes seem to have better odds

Noticed something weird over the last few months. Some slot games with super simple fruit or classic themes feel like they hit way more often than the over-the-top ones with crazy graphics and bonus rounds. I started keeping track out of boredom one night and it almost looks like the plain old-school slots pay out small wins more frequently, even if the big hits are rare. Meanwhile, every time I try those movie-themed, feature-packed slots, my bankroll vanishes in record time.

Curious if anyone else has paid attention to this or maybe tracked it with actual numbers. Am I just falling for some pattern or is there something to these themes and their hit rates?
