A lot depends on the tutor and the cohort you are in. I'm just finishing my first module and am not overly happy. My tutor admitted freely that they haven't read the OU material for years as it's not a good use of their time. So instead of teaching to level 1 standards/ability, they get frustrated when they discuss more complex issues that we haven't studied.
They also don't turn up to online tutorials and then lie saying other people called in and that you are at fault. That resulted in a complaint t and an apology as they did not run the tutorial and I (and other people in my cohort) and the OU were able to prove it.
Other tutors have gone AWOL mid - course leaving students waiting weeks for TMA results. My tutor won't take phone calls or texts but doesn't reply to emails promptly.
The materials are out of date in places and quite often supporting materials have been missing. People with disabilities have struggled to get the appropriate support, ie printed materials or extra time due to dyslexia.
The standard of tutors seems to vary largely some cohorts get a lot more help and support, unfortunately mine isn't one of them. If you don't live near one of the hubs where they do face to face tutorials it's all online and can be isolating.
I'm starting a new module in October....if I have a poor experience on tat module (it's a different discipline and faculty), I'm transferring to a brick uni.
