i'd go a bit further than that since the cited ref supports what reverted to that text is valid even if you don't like it if you are going to alter text that is based on a cited source check the source to make sure the text in the article is or isn't supported provide an edit summary as to why you are changing the text if your edit is disputed take it to the talk page the edit you made to x men first class film appeared to be capricious at best but in conjunction with reverting a spelling correction and filing an unfounded vandalism report against an editor you are edit warring with speak to bigger problems right now i think it would serve you well to read over wikipedia vandalism wikipedia harassment wikihounding wikipedia harassment user space harassment wikipedia assume good faith wikipedia disruptive editing at the very least
