Um...I guess that was a good episode. Weird concept, though nothing truly mindblowing (heh). Patrick with no eyes looks somewhat creepy though and that old man capturing the brains? Eye (heh x2) don't think he had the most pleasing face to look at.
As for the humor, well, Squidward thinking they're invaded by Martians was really funny. There was some other minor gags such as the Mr. Krabs and Mrs. Puff date (!!!) but otherwise this episode was pretty light on jokes. The episode does remind me of Pranks A Lot because it's the same pranking motif as that one. This episode is better, though.
I wish they would have made a nerd joke in there somewhere...you know, because they're also brainiacs? ...sorry, I'm not sorry. (heh x3)
Also, I have to mention the animation because it was quite...something. The characters feel very expressive...even when they don't have eyes. I really like the animation in this episode (and probably the rest of the season) and it's a very interesting mix between season 9b's animation and seasons 2-3's animation. All in all, it just works.
So...what's my overall thoughts on the season opener? It's pretty good but I can't give it higher than 7/10. With such an insane concept, mind you (heh x4), I would expect a bit more insanity and while I got that from Squidward, the rest is pretty standard stuff for Spongebob.
It's not the worst episode, though...well, duh and it has no big flaws to point out. It's simply a good episode. For the next episode, MermaidPants...they really need to up the ante because I looked at that plot synopsis, and from that I think that the episode could be absolutely fantastic!
Guess we'll have to watch and see whenever that comes out?
Bluey, out.
