I haven't seen a show at wembley arena and am trying to work out whether it'll be worth getting £50 tickets or whether the view will be gash.

I've watched a few shows from the stands and never had a problem. Nobody seemed to be complaining either after Sprott-Harrison and Thompson-Haye, in more recent times.
Wembley used to host boxing almost every other week until the sport became less mainstream from the 1990s.

I was at Haye-Thompson and I thought it was a very good venue. Get yourself on the 1st tier balcony if possible
