Overall for the series, I generally liked it. I think there were some parts that were a little cliche, but that's okay. Also, some of the "villains" felt a little flat and one-dimensional, but it wasn't overly bad.
Regarding the ending, I'm just saying this for anyone who didn't notice. I think Ari is missing an arm now. Gaya is obviously wheelchair-bound. My issue is that the police had apparently found two bodies swept by the river? Did... The police find Gaya and Ari and just not tell anyone they were alive? I find that highly doubtful. But then, with their massive injuries, how did they survive? They needed to get medical treatment to...live. If the two bodies the police found were not Gaya and Ari, then who were they?
Ultimately, I am fine that the two survived. That, in and of itself, is an okay ending. But it leaves major plot holes that don't make sense.
