Aside from the obvious Lords of Shadow subbranding and the less than tight controls, I really don't know how you can say that, given that I can apply that same gripe to the Christopher Belmont games which are amazingly loved by many fans. It's hardly the best Castleroid, but it's far from half-baked.
I wouldn't say amazingly loved, at least not the first one. The first one felt like an unfinished game. The second, aside from the slow pace, was much better.
Firstly, I wanna say that I enjoyed MoF. I liked it for what it was. But if I'm gonna be fully honest with myself, there's a lot wrong with it. I find the plot of the LoS trilogy (mostly) easy to follow, so that's not where any of my gripes lies. In MoF, a lot of things take too many hits. Some enemy fights drag on longer than they should, and even things like barrels take way too many hits to destroy (one of the gripes I have with the God of War series, too).
While the first LoS at least tried to be clever in how it handled the combat (with the huge variety of moves and it's pretty free-flowing combos), MoF dramatically dumbed it down to where there were hardly any. The two-button combat of the games didn't transition that well to the 2D plane, and the boss fights were predictable, some of which are outright bad (though the final fight against Dracula ROCKED).
Like the first game, it had a heavy reliance on QTEs, even for simple things like opening chests (thankfully, this was mostly rectified in the HD version). And on top of that, with the amount of characters, the game felt too short. To 100% it, it only takes around 11-12 hours, which is barely above half the advertised 20-hours of gameplay. Had the game been the same length, but solely focused on one character, it potentially could have been better (particularly if it focused on Simon, as I feel he is the most lacking in terms of depth, but largely cuz of how they handled him). As it is now, though, it's not nearly as long as it should be. You barely get fully used to using a character before it switches over to another playable character.
Someone explain to me why Simon had no access to a double jump.
Christopher's games in the classic series are a different story, but also because they're a different kind of game. Whereas MoF is a platform-adventure, Adventure and Belmont's Revenge are both standard stage-by-stage platformers. I already stated Adventure felt unfinished, so I won't go into that. But Belmont's Revenge simply had a speed problem, and the lack of uncontrollable jumps was a little annoying. But I don't even have CLOSE to as many gripes about CV2BR than I do with MoF.
Mind you, again. I do like MoF and I did enjoy it. But if I'm going to be honest, I can see why a lot of people don't like it.
