Yeah, for one of the show's most sympathetic characters, Mac has endured a lot of undeserved suffering. It's starting to worry me.
The ending to "Foster's Goes To Europe" was just vile. I'll never understand why the Foster's crew sometimes insist on wasting their talent on such viciously cruel and meanspirited episodes that do nothing but hurt the viewer's feelings. I REFUSE to see the humor in how Mac tried so hard to get everybody ready for Europe, only to get screwed in the most heartbreaking way possible.
I originally thought "I Only Have Surprise For You" was fine, but after thinking much over it and reading Mr. M's harshly negative feelings on it, I now see the true horror of it.
And, of course, Bloo is often pushing him around and dragging him along for his schemes.
I really hope that, for a future episode, Mac will outsmart and one-up Bloo for a change.
