Both were OK, IMO. "Baseball Blues" seemed to me like a George version of "Arthur Makes the Team". George isn't very good at baseball, and even shows a bit of jealousy towards Francine at times. When Francine gets sick, he goes through several people's cell phones and discovers he has a great talent of play-by-play announcing while doing so for Francine over the phones. One of the phones George was using looked exactly like the iPhone. Only a matter of time before we saw that in the Arthur universe. Harry Mills, Carl, and Brain's mom make their Flash debuts, and I think Mr. Frensky as well (was he in the first half of S16 at all?). Carl looks the same, and I don't believe he had any lines. Harry I believe has a new voice and now has buck teeth. They don't look good, IMO. Brain's mother appears in both episodes, and she has reverted back to her original appearance! (light brown skin/fur and dark brown hair) I actually think it works better for her, though.

I don't know why "Brain's Biggest Blunder" was titled as such. Maybe to keep with the alliterative B theme? With the story being about a math competition similar to that seen in "It's a No-Brainer", but with 3-person teams, you'd think Brain would have made a fatal mistake like in said episode when he said trapezoid instead of traingle. It turns out the "blunder" was him overworking Buster through really hard tutoring. Binky tutors Buster and it works out for them. Buster solves multiplication problems by thinking of layer cakes. (12 x 3 = thought bubble of three 12-layer cakes)

The Flash seemed pretty lazily done in "Baseball". The worst thing about any Flash show, IMO, is how characters often "sway" or "bounce" when talking or changing facial expression. This effect really shows in the scene where everyone is in the ice cream shop. There were some points in "Blunder" where the Flash was barely noticeable. For me, in all the new S16 episodes I've seen, the Flash seems to keep switching between "Tolerable" and "I'm considering changing the channel". There are times where it has the old "frame-by-frame" look, usually when Arthur is seen at a side angle. He looks and talks (concerning mouth movement) exactly like he always did. Other times, it looks like something a teenager posted on Newgrounds. A great example is near the beginning of "Sue Ellen Vegges Out" (currently on YouTube) when Buster is poking Sue Ellen's food with his fork. It is also made obvious that Buster's head has only been drawn a small amount of times, because whenever he's facing front, his right ear is always bent in some odd way that I never noticed on the old animation. That really bugs me.

Also, I know the show, like many children's shows, are fond of recycling characters' gasps and such, but they need to let George's actor record some of his own. He gasped twice in "Baseball" and it was clear they were taken from other characters' VA. The second time was actually Buster's gasp (I'll compare them if "Baseball" ever shows up on YouTube), and I remember during one episode (I think "George Blows His Top"), George groaned using Michael Yarmush's old Season 1 Arthur groan!
