You just need to try harder. It might be just the barrier that they feel bit more clumsy at first and then the sprite graphics. But if you keep playing for few hours you'll begin to appreciate the game more and how it feels.
I would recommend you to install crt emulation to get most out of how the games are supposed to look (instead of using shitty scaler as what most people seem to unironically be doing), and also recommend using MT32 emulator or good general midi soundfont to get most out of the audio.
So, it comes down to 2 things: 1) setting up dosbox and your gaming environment in a way it's as good as possible (including adding patches for proper mouse support and modifying keyboard controls to suit your own preferences) and 2) spending more time with the game than just 20 minutes before deciding if it's good or not.
Most people are too ignorant and lazy that they expect everything to be handed automatically to them without any effort. Take a look at these pixel shaders. I prefer the scanlines most as that reminds me of CRT, but most people don't ever do that because they are too stupid to customize anything in their game.
