Do you like BrickHeadz and/or Monsters, Inc.? If so, this might be the LEGO set for you.
Pixar’s premiere monster power couple Mike Wazowksi and James P. Sullivan haven’t been blessed with the same kind of LEGO ubiquity over the years as other notable characters from films such as Toy Story and Cars. WALL-E, Up, Inside Out and Brave are all better represented in LEGO form than the humble workers at Monsters Incorporated, no matter how close they are to beating the All-time Scare Record.
Until now, Mike and Sulley have been left waiting on the shelf, alongside the disembodied dad legs from Onward and Flik from Antz A Bug’s Life. (At least Flik got to make a cameo in the LEGO The Incredibles video game.)

Finally, Monsters, Inc. has been given a turn at the LEGO table, and if getting a cute, blocky version of these characters is all that you care about, this set delivers exactly what you need. If you’re a fan of BrickHeadz, all the better.
There’s not much by way of innovation or experimentation here – Mike, Sulley and their temporarily adopted human child Boo click together in much the same way as any other BrickHeadz set. First comes a cuboid with SNOT pieces on the sides, then layers of plates and tiles create abstract details to set these aside from other licensed characters. Sulley’s horns are fun and Mike’s one big eye is spot on, but otherwise these three builds don’t deviate from the established formula.

This is far from a negative – the whole point of BrickHeadz is that uniformity.
Even the price of this set is entirely within the expected range for a BrickHeadz set with three characters. It's possible to quibble over whether two shorter figures and one slightly taller figure balance out when compared to similar sets of this size, but ultimately, this slots neatly into the LEGO Group's current BrickHeadz portfolio without ruffling a single price-related feather.

Alternatively, if you’re a Monsters, Inc. fan who has never really paid much attention to BrickHeadz before, there are far worse places to start. These little figures deliver a nice little furry punch of recognisable licensed fun without breaking the bank, and while it might be nice to eventually get a LEGO set with a bit more distinct Monsters, Inc. flavour, it’s hard to fault what has been offered up here.
Just be warned: the whole point of BrickHeadz is that they’re dangerously collectable, and there are plenty of other Pixar BrickHeadz sets that would sit very nicely next to this adorable monster family.
Our honest opinion: 40861 Sulley, Mike and Boo Figures delivers a small dose of Monsters, Inc. nostalgia in a familiarly shaped package. Fans of BrickHeadz, Monsters Inc, or both will no doubt smile while building, displaying, and playing with this set.
