I liked him. They could've made the "boy genius" storyline a bit better, but then the "genius" part overlaps with Data too much I guess. Also, he shouldn't have had issues getting into the academy at all
He’d have been so cool as like a prodigy type, that’s where I thought they were going with him making cool gadgets and understanding traveller. I really wish they’d just gone through with it, since the best and brightest are supposed to be the very fabric of starfleet no overlap should be a problem.
Well, you generally don't want your characters to be redundant though. A boy genius finding it hard to integrate with the crew (which was where it was heading, with the famous "shut up Wesley" being an example, or that Picard didn't want children on the bridge) is quite close to wondorous machine that doesn't fully understand what it means to be human finds it hard to integrate with the crew etc
I like Wil but his actor skills are gone. His appearance in Picard was cringingly bad. Although I partly blame the director for allowing such a bad performance to go to print.
I really liked him in Eureka. I don't think his acting skills have gone all that far downhill since then. And I'm not sure what sort of performance you expected from a superbeing Wesley.
I expected something like Wesley from the TNG episode, Journey's End where he was fantastic. Instead it was like if you put Adam Savage on set and told him to geek out about being on Trek.
