Recommendation: yes 5 / 5

This LEGO set is great for roleplay or display. Fans of the TV show will really appreciate the attention to detail in this set and discovering all the little familiar items from the show.

Recommendation: meh 4.8 / 5 from 383 reviews

OK so I'm a 60 year old women and I've never been into Lego's, however I am a HUGE Big Bang Theory fan and just had to have this - This was the very first Lego I have ever done. I love the instruction book with a picture of each step - that is great, It took 5-6 hours to put together and it was really fun. I loved that it was relaxing and the whole world just kind of "went away" while I was working on it. I think I might just be a Lego fan too. PROS: Easy to put together, no missing pieces - in fact a bunch of extras, Great instructions. ADORABLE BBT apartment & cast. CONS: now I have to find another Lego Project- and they are a bit pricey.

Nice build. I would have liked to see more of the room and the kitchen it could have easily been a set that swings open. Mini figures are pretty realistic.

The quality of the box, manual, and set are all really excellent. It's exactly what you'd expect an Ideas set based on the BIg Bang Theory would be like.

The interesting thing about LEGO Ideas sets is that they're all so individual. You can easily skip a set if you're not a fan, or collect them all for the fun of it. There are some set though, that just need to be grabbed if you're a fan of the IP itself, and this is one of those sets. If you're a fan of TBBT, you'll want to get this set while you can.

Recommendation: meh 4 / 5 by Nick Martin

Despite my feelings of the show, this is an absolutely solid set. It's a display set through-and-through, but there's outstanding value for minifigs and some nice little extras mixed in. Seven minifigures that each feature some unique stuff, and complex printing on legs and arms all make for great value.

Recommendation: no 4 / 5 by Allen "Tormentalous" Tran

A nice little vignette set that resembles the real-life counterpart very well. The only thing that's sort of out of place is the setting of the minifigures on the box and in the official images. A few of them are sitting at a different position that they normally sit in on the television show. I've kind of rearranged the minifigs to their typical spots that they are seen in.

I find this set very interesting. Maybe because I am a fan of TBBT series. Set has many, many parts. If someone wants to make some stop motion vidios here he has a stage plan, actors and props.

As a non-fan would I buy it? As a collector of LEGO Ideas sets, yes I definitely would, but if I wasn't one, I'm not sure. At US$60 / €60 and (probably) £50 it's not cheap: better value for money, and more excitement, can be had elsewhere in LEGO's range. However, there's undoubtedly a lot in it that will appeal to fans and if you are one then it's a no-brainer if you can afford it.

The Big Bang Theory is not a particularly exciting build in terms of techniques, but I very much enjoyed it, because I could slowly see the living room that I know so well from the TV series grow and because it is chock full of nice details to appreciate. The figures are excellent and the finished product looks the business.

This is a set almost entirely targeted to fans of the show. For them, the set will surely appeal mainly due to the high quality minifigs, and they'll be enthralled by the highly curated reconstruction of all details from the show. It's a great display piece and a perfect "geek" gift for your friends who are fan of the show but not (yet) of Lego. For everybody else, this sets has little to say. It has seven generic (albeith well done) minifigs and half a room with lovely furniture and no play feature whatsoever. Even as part pack, unless you're interested in some of the unique printed pieces, there are cheaper options.
