Adapting to a new home after spending 133 years at Goodison Park was never going to be easy, but Everton's settling-in period at Hill Dickinson Stadium is taking longer than most expected.
David Moyes' side began well enough, winning two and drawing two of their first four, but are now winless in their last five home league games.
Before kick-off the Toffees boss said he would like his side to replicate their impressive away performances in front of their home fans, and for a time they did.
If Barry's glaring first-half miss let Bournemouth off the hook, then the Cherries had goalkeeper Petrovic to thank for clawing Ndiaye’s back post effort off the line and onto the woodwork.
Superb goalmouth blocks denied Kiernan Dewsbury-Hall and Barry early in the second half, before Everton's night fell apart in the space of eight minutes.
The ease with which Bournemouth twice opened up Everton – having created little beforehand – should concern Moyes, more so than O'Brien's avoidable red card.
The defender felt he had to try and stop Adli racing onto a through-ball in behind, and even though he was still more than 30 yards from goal, he was the last man.
