This is a common complaint, but I think the controls are actually very tight. Usually the issue is that the player is struggling with travelling in a vacuum with a ship that can quickly get up to tens of thousands of km/h and it's very difficult to judge distances in space. I realise you're unlikely to go back if you've read a story synopsis, but for anyone else I would highly suggest locking on to your target and using the two numbers (your current speed relative to the object and the distance from the object) to judge how hot you're coming in.
