Just finished it, wasn't the best episode to end on actually felt very rushed and I got the feeling the writers are glad to see it over with for now.
Jiren has nothing left after his wars with everyone which is understandable considering he has taken on the best of Goku, Vegeta, Frieza, Kale, 17 all on his own essentially which when you think about it he is by far the most powerful and if he just had a one on one with any of them then he would wipe the floor with them.
He has a last attempt power up but I noticed they made a point to show that even with that he was only matching Goku in his normal state and Frieza in his normal state so they was emphasizing at this point Jiren was exhausted and beaten and I like that as no one can just keep going
I loved how Frieza went full savage mode on Jiren when he had him beaten but as usual his cockyness almost cost him.
Goku is one hard bastard but we all know that, the guy just don't stop unless you actually kill him.
Heavy theme here that trust and friendship prevails against all and it was pushed hard here, it basically came that no matter how strong and powerful you are you can never overcome love and friendship.
Overall this was rushed and didn't feel epic at all to be honest, kinda disappointed really.
Oh and Zeno knew all along U7 would win and you basically had to wish the other universes back otherwise you all get erased.
