What do you think of VAR?

Just watched Burnley vrs Bournemouth and Burnley won 3 nil.

Really weird decisions though made by the video ref. Bournemouth had a goal disallowed in the first half. Later Burnley had a hand ball appeal in the Bournemouth box which the ref waved away and then Bournemouth equalised on the counter attack. However, the video ref then went back to the handball decision and gave Burnley a penalty whilst also nullifying the Bournemouth goal.

I generally support VAR but it's been badly implemented. Nobody knows what is going on half the time.
