Beyond Selidor

I agree with your assessment of all the shows — as you say, season 3 of Broadchurch was a vast improvement on season 2, but there was no real reason for it to exist, as season 1 was complete and perfect as it was. I think our opinion of Veronica Mars is fairly universal. There are moments I enjoyed in the later seasons, and as a Logan/Veronica shipper, the pure, fan-servicey existence of the movie brings me joy, but there was a serious dip in quality after season 1, and it never really picked up.

Weirdly with Pretty Little Liars I actually didn't mind the Aria/Ezra relationship (in fiction; obviously in real life I'd be appalled, and I think Ezra's actor felt similarly — I remember interviews where he said he was shocked that the relationship was played as romantic, when, as he said, 'my character is a predator!') — the one I found frustrating was Spencer/Toby. I feel that the showrunners caved a lot to fan pressure, so when a character or ship was popular with fans, they'd retcon any reveals that painted the character in a bad light, and handwave away any of the character's wrongdoing.

Paper Girls has been on my list of things to watch for ages — as you say, it seemed to appear without fanfare, and disappear without a trace.
