Not a 5 star to me.
CGI, great! Plot? Really? No plot involved, but maybe, definitely, a pot. The one Snoop Dogg smokes up.
Some of the dialogues that happen for a ridiculous long amount of time, have absolutely no impact in the story ahead. They've desperately tried to put emotional conversations in places with bad acting that just don't stick, let alone arouse any emotion from it, let alone inspire the actions of the protagonists based on it.
A very average movie with fancy CGI. Skip through the dialogue, watch the action, trust me, you missed nothing.
