It wasn't a bad watch but there are other prison films that gives better entertainment and gripping moments.
I do believe some of the scripts could have been better executed and shortened, there's no reason for us viewing 40-50 seconds of no action or words. I get they were probably trying to be dramatic but it felt so over the top. And don't get me started on the love between the main character and her daughter, I also think this was overplayed and for the daughters age (18) she acted and was treated like a 10-12 year old.... ridiculous.
One murder wasn't solved (the warden's) which was what gave the rest of the series a storyline (found this a bit wrong really).
Episodes could have been shorter, some bits were predictable, whilst some characters I think overplayed their role and it went on a bit too long with no real momentum.
It's watchable but not something I'd rewatch.
