The problem I have with most of these services is that every channel is too hyper-specific, often literally just playing a single show or, at best, 2-3 shows but in multi-hour blocks. Incredibly lazy IMO.
To me, the appeal of linear terrestrial TV is having channels that show a wide variety of things throughout the day. If I wanted to see 24 hours of non-stop Mr. Bean I’d download them and shuffle the folder.
