While I did enjoy "Blondie's Reward" I am deducting a point for one grotesque scene where Alvin pretends to be mentally deficient. It's terribly acted and just gross.
The rest of the story is quite good. Dagwood is instructed to buy a valuable piece of property for his boss but instead buys some swampland from some crooks. Naturally Radcliffe is angry but instead of his usual (firing Dagwood) he demotes him. But, through a mix-up the demotion doesn't last long. Dagwood is supposed to pick up some papers from a client but a neighbor (a former pro footballer and All-American) does the errand for Dagwood. There, he encounters a brutish jerk who attacks a woman and then him...and the All- American ends up knocking the crap out of the jerk! Now you'd think going to a client's home and hitting someone would be a problem...but the client is thrilled...he hates the jerk and loves that Dagwood (or who he thinks is Dagwood) taught the guy a lesson on manners. What's next? Well, Dagwood has his old job back and all appears to be working out fine...until the ruse is discovered. What's next?? Well, A LOT!!!
Overall, despite the nasty scene I mentioned, a good installment of the series. Worth seeing, though it is certainly insensitive.
