No matter how much goodwill there is to Wolverine for teaching the world that there was space for a Ryan Reynolds-shaped Deadpool, there's not a great deal to love about the first (and only) X-Men Origins.
The opening sequence that sees Logan and his newly cast brother (Liev Shreiber, who is mostly as excellent as Reynolds, in all honesty) is great, but pretty much everything else is provocatively bad. There's not even kitsch value (aside from the ludicrous cameo by Kevin Durand's Blob), and pretty much every decision looks like a mistake in retrospect (especially casting Will i.Am and fatally sidelining Gambit).
Yes the Weapon X story was a good foundation, but it didn't go far enough, and the brief sequence in X-Men Apocalypse on the same subject makes this entire film look shoddy by comparison.
Unfortunately for Fox, the film was so badly received it partly killed the potential for the superior sounding X-Men Origins: Magneto. But at least we did get to see part of the Nazi-hunting plot at the start of First Class.
