I kept on wondering where in the hell his character came from because they were apparently looking for Justin Theroux but after a quick close-up he is forgotten and by complete coincidence they find Del Toro instead, who fulfills the exact same function. Even though I only saw the scene once, I’m pretty sure Maz said that Theroux’s character was the only person capable of performing the required task. It seemed like quite an unbelievable coincidence, then, that Finn and Rose just happened to share a cell with a suitable replacement.
The escape to a hidden planet seemed especially dumb, even more so considering that they are discovered and nearly obliterated. The explanation about getting a better signal to call for help seemed nonsensical, even for a space opera.The whole charge towards the cannon was pointless, although I suppose in truth I never expected them to actually kill off Finn. However, it was just a waste of 10 minutes of screen time to set up their attack, their failure, and then Finn’s sacrifice, only to nullify it almost immediately.
