I think the LotR theme has a great deal of potential. But looking at the initial offerings in this first wave, I do have some concerns regarding their choices and stylings/aesthetics. Especially if they are as expected targeting an older 12+ and adults range.
The sets being offered seem to have a similar issue with some of the potc non ship sets. they are trying more to portray scenes rather than places or distinctive things such as vehicles. This results in some somewhat schizophrenic sets that end up as a couple of oft repeated minifigs, some half walls and scenery and maybe a big monster thingy. over in the Star Wars line, the Hoth Wampa cave is a neat interesting little set. it works because the rest of the line is all vehicles or distinct places. A whole line of Wampa caves simply wouldn't work as well. And that is kind of what the first series of LotR seems to be.
Of the initial offerings, the only one that jumps out as a true show stopper. The perfect Lego LotR kit, is Gandalf in his little cart. It sings of everything we want. But Orc Attack? Helms Deep has some potential, but still feels a little off from what we can see. Not one thing or another yet.
We want a nicely detailed Bag End, a full building Prancing Pony, a 900piece Rivendell. For smaller sets please something a little more than a few figs and a partial wall. That's what sort of suq'ed with some of the potc sets. Woohoo it's got 2coaches and 2walls of an inn. Bleach!
And I hope they shake up the colors a bit. While middle earth is more earth tones on film, please back away from the grey bricks just a tad. Shake up the scheduled offerings to at least toss in some green and brown themed sets, so it all doesn't feel the same on the shelves.
