I agree with this. But for so many reasons: TV shows are usually built differently.
They have options a movie hasn't - world building, character development.
They are "bitesized" by design: a convenient pre-made cut that I can decide to take a break on, or watch the next episode.
That said, I have seen so-called miniseries that were just a longer movie cut into bits, or vice versa.

But most importantly, all this depends very, very much on the quality of the show or the movie.

As long as either ones actually gets a proper ending.

So many tv shows are just some CEOs checklist of products that they need on their platform. Netflix has a successful spy thriller? Now Amazon and Hulu are going to pump out a copycat slop to satisfy their greedy yearly quotas.

I can’t commit to spending my time with a product that can’t even respect the customer enough to properly finish making it.

TV series have spoiled me with an actual storyline. Movies just seem to cram as much as they can into such little time that most of them just seem lacking to me now.

Some stories work better as movies, some work better as a series.

Shows have the advantage of having natural breaking points. You don’t have to watch the whole movie at once, but it’s paced that way.

I find that there isn't the time for a movie to world-build in the way that a TV series can.

Completely the opposite. I get 3 episodes into a show and I almost always lose interest. Films are great cause I sit down once, watch the thing, and then move on with my life. Getting into a new show is like a marriage I didn’t ask for.

I do so long as I can fast forward the boring bits! I haven't sat in a cinema with no control over pausing and fast forwarding in years. (Edit: I should say I've got ADHD so that's probably why lol)
