There is a lot of talk in the thread about size / price / piece count, so rather than respond to anyone in particular, I thought I would just throw my two cents worth in.
Firstly, the size of the buildings – or rather the height. Yes, the the apartment in particular is “short” compared to other modulars, but you have to remember that unlike an MOC, these things are built to a budget – and therefore built to a piece count.
The biggest aspect that affects the piece count in this set is the fact that we have two independent buildings. Two buildings means two dividing walls, which means that there are less pieces available for other things.
With this limitation in place, you have two options: smaller or less detail. The apartment has compromised a bit on both of these – the basement is pretty empty and it is reduced to a crawl space. Personally, though, I prefer this to the way that the other split modular got around this – the Pet Shop, which had the completely bare apartment “under renovation” in order to not have to put in interior detail.
Detail versus size has also been compromised in other sets. Everybody loves the Parisian Restaurant now for its detail, but at the time it was well noted that this detail came at the cost of building volume – it was a clearly smaller than those that came before it. The Corner Garage was criticised for the empty ground floor and the rather plain exterior (even though it actually took a lot of tiles and other parts to achieve the look). Look back further and you’ll see that the Palace Cinema was pretty empty and that interiors were not even important enough to include on the first modulars.
Every set put out is a compromise between competing wants. You want a big, impressive building that looks good on display? Fine, but don’t expect hundreds of small parts chewed up in creating detailed facades, or forget about the interior (which most people won’t even get to see on your shelf). You want intricate builds with all the new pieces (most of which are small), then don’t expect it to be big.
This set will not please everybody. No set can. So if you don’t like it, then it’s probably because one of the compromises goes too far for your taste. Personally, I really like it. Is it perfect? Of course not. Do I appreciate it for what it is? Yes. Will I be getting my kids to build it from the instructions before learning from it, completely modifying it and then using it as a parts pack for other things. Definitely.
