In my opinion, LEGO has only gotten better
over the last few years, and I don't think that'll change anytime soon.
Not everyone will be aware of this, but during the 1990s and early 2000s, LEGO was in serious financial trouble - they were losing money. A lot of this was down to bad decisions when it came to innovation and direction. That all changed in 2004, when LEGO appointed a new CEO who brought around a few changes in mentality for LEGO. Since then, the brand's made a comeback - in a big way.
Over the last few years, we've had a bunch of old lines - long since dead - rebooted. Kingdoms replaced the old Castle line, and honestly? I think it's a heck of a lot better. We've gone from this:
To me, that's an improvement. LEGO has updated the design while still maintaining some of the 'old' and blending it with the 'new'. The castle has the same basic structure, only now it's a little more decorated and a little more playable.
The same thing has happened with a lot of the 'revamps' - Power Miners, NinjaGo, Pirates and Pharaoh's Quest to name a few. A lot of the old sets have been updated for a new generation, with smarter construction, better designs, cooler minifigs and some neat concepts that distinguish them from their spiritual ancestors. Sure, Raines is no Johnny Thunder, but he isn't meant to be.
LEGO has also come up with a bunch of new themes you seem to have skipped over. The 'Fantasy Era' line they released is one of the coolest I've seen - I mean, it had orcs, dwarves, elves, armies of skeletons and heaps of new parts and sets! That's hardly the only line they've come up with; Space Police was pretty awesome, as was the Agents line. The upcoming Monster Hunters sets look sweet, and don't forget the Collectible Minifigures line which continues to amaze me. Sure, some of the ideas have clearly drawn from older lines, but that's not a bad thing.
And don't dismiss the licensed sets. Although some of us are sick of Star Wars by now, the sets are still pretty cool and throw out a bunch of new parts with every release. We've also now got awesome lines like the Pirates of the Caribbean sets, Marvel/DC, and Lord of the Rings - who wouldn't
want their own Jack Sparrow, Iron Man and Aragorn minifigs? Some people might moan and groan about the flesh coloured figs, but oh well - you can easily replace most of the heads and hands with yellow replacements your own collection, and all that'll really happen is a slightly mismatched neckline for some figs. Besides, if licensed sets aren't up your alley, just remember - LEGO is a business, and licensed sets sell. If they're out there making money that lets LEGO make more awesome original themes, then fantastic!
Finally, don't forget that LEGO is a business, and a lot of its decisions have to be made from that perspective. As sad as it is, businesses need to make money, and although LEGO seems to try to be good to its AFOL and TFOL followers, they're ultimately not the primary market. LEGO has to play to its core group - the kids - and anything else is really just a bonus. Sometimes, this is great for AFOLS and children alike; kids get to have Aragorn battle Shelob while they fire missiles from a ballista, while AFOLs finally get Lord of the Rings sets they can build dioramas from and use in their own creations. But sometimes, the nature of LEGO means AFOLs get a bit disappointed - and in this case, it seems LEGO tries to find a comrpomise. The Collectible Minifig line seems largely aimed at AFOLs; LEGO might not be able to make a line featuring zombies, but they can sure throw together a minifig for us to nab.
When it comes down to it, LEGO is a toy, and toys are made for people to have fun with. As long as LEGO keeps making bricks, I'm sure even the grumpiest fan will enjoy playing with them in their own way.
