"I Am Groot" (no spoilers please!) :-)

Thanks for adding no spoilers to the title, Im still waiting for this and Logan on blu ray. Im not a fan of cinemas as my PC + Headphones audio is better :p
 
Is the first GOTG worth buying though? I heard its not as good as the second one, and I already have marvel unlimited and havnt yet started reading GOTG or Deadpool, but want to at some point (theres too darn many of them, I was mainly focusing on X Men and Avengers, now Im into the Inhumans, Doctor Strange, Scarlet Witch etc etc).
 
Both the first two Wolverine films were pure meh, I already bought them and didnt really like them much.
