J.B.'s Submarine Reviews
Brickset
“Hidden Side has yielded an outstanding selection of unusual buildings and vehicles but 70433 J.B.'s Submarine is among the weaker examples. The minifigure selection is good and I like certain aspects of the underwater scenery, although I believe there was potential for more... More detail and this environment provides little evidence of its location underwater.”

The Brothers Brick
“This is a quick, fun build, but if you are looking for something a bit more complicated this might not be the set for you. However, it's sure to please younger builders and parts junkies. In particular, I really like Parker's new hairpiece, the black seaweed and the medium... More azure branches. The minifigures are quite nice and the combo of those plus the plant pieces make this a great set for those of us that mainly collect sets for their interesting parts.”
