Okay, I'll admit it-- LoS was a complete and utter disaster for fans. I wouldn't have been quite as offended if they hadn't tried to pass it off as a Castlevania reboot while killing everything good about the series.
In that sort of vein, I guess you do have a point-- if buying all that DLC is the only way to prove I want more of the original series in 2D form.. well.. I guess it's worth putting some money in as an investment for a future more desired.
Doesn't make me any happier about the prices, though.
