I don't think Big Show can be blamed, its the WWE writers and bookers who put him in the roles, matches, and gimmicks he's in. If Andre was wrestling in this current era it would be the same exact deal for Andre, and that's what people miss.
The good the bad, between the two though;
Big Show:
+ wrestling
+ talker
+ bumps
- size
- booked too much
- Raws are now more like 1980s PPVs/SNME's weekly
+ we get to see him wrestle more often
+ extremely talented in the mid 90s
+ it factor in the mid 90s
+ had the look of a champion in the mid 90s
- bad booking, worse storylines, short feuds > the current generation
Andre:
- wrestling
- talker
- bumps
+ size
+ brilliant booking in 1987 only wrestling 3 matches on tv?
- only seen in a match maybe once a month to once every 7 months
- we didn't get to see him in many matches in the 80s
+ very skilled wrestler in the 70s
+ better booking, better storylines, long lasting feuds > the 80s
So it can really go either way, I'm a big fan of Andre and what he did in the 80s, but it being a totally different time in wrestling really makes the difference, I mean hell look at the top of the company at the top dog Cena, Andre never went through a rapper gimmick, and Andre never went thought fans chanting YOU SUCK, or CENA SUCKS, or LETS GO CENA, CENA SUCKS. And neither did Hogan, Warrior, or Savage, let alone Andre, just a different time in wrestling.
When its all said and done, and Big Show is done with wrestling for good, and we no longer have a big guy that size in the WWE, so long as someone else that's over 7' and 400lbs doesn't come around, guys should be looking back at the ladder matches hes been in the last couple of years and you'll be amazed at what he did. I know Andre use to jump off the top of a cage back in the 70s and maybe early 80s when he wasn't so big, but at Big Shows current age hes still doing it, cant say Andre was. Big Show is at 41 years old now, he was in those ladder matches in his late 30s, Andre in his late 30s was only wrestling a couple of times a year on tv (1987 Andre would be 37 years old) mean while 37 years old for Big Show he was wrestling on a weekly basis a good chunk of the year.
