a) Too much like 'Hellraiser' and 'Deadstar'
As a basic concept, Event Horizon began to sound like Clive Barker's Hellraiser set in space which sounded like what Bill Malone's original premise for the film originally called "Dead Star" aimed to be with the devil unleashed aboard a space craft.
The development of the "Dead Star" project was brought to a halt by the end of 1990 and later it was transformed into something else quite different when Walter Hill later got his hands on the script and turned it into the film "Supernova" released in 2000.
While the plot of Hellraiser was different enough, unfortunately the image for many making the connection between the two films transformed Event Horizon into something highly derivative.

b) Acknowledgement of "Hellraiser "
Paul Anderson and his producer were inspired by the transforming nature of the Lament Configuration Cube from Hellraiser, which does suggest that they saw Barker's movie and were aware of the similarities
- Jeremy Bolt: We were quite inspired by the cube in Hellraiser and the way that it realligned itself and reshapes itself. (Event Horizon DVD commentary)
c) Doctor Weir too much like Pinhead
Sam Neil's character Doctor William Weir utters the words "I have such wonderful things to show you" before gouging out his eyes
This echoes Pinhead from Hellraiser's utterance to those who have just solved the lament configuration and opened the portal, "We have such sights to show you"
